4 - 6 month old baby

Baby's development at 4-6 months

A lot can happen from 4 to 6 months – rolling over, learning to sit up, trying solids for the first time and even forming first words. Your baby’s development is becoming even more dramatic which means that soon they’ll be getting some of their much-needed nutrients from solid foods, although milk will remain their core diet for now.

Read more about what you can expect in the coming months; your baby is now able to learn from you, which is especially important for speech development. They’ll soon be able to sit up too, which will give them the independence to support themselves. You can also read about how to tell if your baby is ready for weaning and, if your baby is ready, where to begin.

Baby's development at 4-6 months

Once your baby reaches 4 to 6 months, you may be starting to think about preparing for weaning. Government guidelines advise waiting until 6 months before weaning, and definitely not before 17 weeks. Although milk should be the main source of nutrition in your baby's diet for some time yet, your baby’s increasing activity levels will soon mean solid foods become an essential part of their healthy, balanced diet.

Other changes happening at 4-6 months:

Weaning Signs

Once you begin to spot the signs your baby is ready to wean, provided they are old enough, you should begin by introducing smooth purées in roughly the consistency of double cream and in gentle flavours. Aptamil Creamy Porridge  is ideal as a first weaning food, or try a baby rice which can be mixed with their usual milk for a familiar taste. This will make the transition easier and help your baby to accept the unfamiliar feeling of the spoon and the texture of the food that’s on it. Puréed carrot is also a perfect first weaning food as carrots have a natural sweetness which babies love, teaching them to enjoy vegetables from an early age. Introducing these sweet vegetables early on will pay long term dividends.

A teaspoonful or two a day to start with will ease them in gently. It may seem like a very small amount but weaning is a very gradual process. If you're bottlefeeding, a follow-on milk can also prove a good source of nutrition once they are 6 months or over as they are specially developed to complement your baby's weaning diet and give them the iron that they need at this stage. If you’re thinking of switching your baby to a follow on milk, why not speak to our feeding advisors on 0800 996 1000 for tips on how to make the transition as smooth as possible?

Your baby 4-6 months

Sitting up

Your baby is on the verge of a new set of developments. As their arms, upper body and neck become stronger, they’ll soon be able to sit up, wriggle and roll around. If their newfound agility makes nappy changing more tricky, moving the changing mat down onto the floor will avoid any accidents and never leave them alone for any length of time.

The floor is also an ideal place to play. Place your baby on their tummy and encourage them to stretch for toys that are slightly out of their reach. This will strengthen their stomach muscles and provide the ideal opportunity to roll over – an important milestone in your baby’s development.

A better grip

Your baby is discovering how to use their hands and fingers through everyday acts like grabbing for a toy or dangling mobile and clutching at things nearby. As your baby’s natural grasp reflex gradually turns into more controlled hand and finger movements, they’ll be able to explore objects by grasping and shaking them with their hands rather than simply sucking on them. If you’re using a bottle, allow your baby to hold it with both hands – it will improve their grip and free you up to do other things.

An improved view

Your baby’s eyesight is improving – they can now see further and focus better, even as far as their toes. As their world becomes a more entertaining and colourful place, it’s a good idea to keep your hair tied back or glasses out of reach. By 6 months their eyesight will have improved even more and they’ll be able to see across the room.

Research has shown that LCPs (long chain polyunsaturated fats), such as arachidonic acid (AA) and docosahexaenoic acid (DHA) found naturally in breastmilk, play an important part in the development of your baby’s eyesight. So consuming more LCPs whilst breastfeeding will help maintain your natural stores and ensure your baby gets plenty of LCPs in their diet too, which may improve their visual and brain development and movement skills.

Finding their voice

At 4 – 6 months you may well be amazed at the range of new sounds that your baby can make. Along with coos and babbles you may even be able to hear ‘ma’ and ‘pa’ words. It may be a while before your baby knows to call you ‘mama’ by name but it’s nice and incredibly entertaining to hear, nonetheless.

You might also begin to hear genuine laughs or giggles – especially during playtime. Tickling is the most obvious way to encourage laughter. Enjoy laughing along with them - which shouldn’t be difficult  - as this will also give them positive encouragement.

Learning

Studies have shown that chatting and singing to your baby can aid speech development. Although they might not be able to understand you, your baby will be able to process the sounds and eventually copy what they’re hearing. Simple, daily interaction – whether it’s talking, laughing or smiling will help them to develop.

Another way to aid learning is to fill a plastic container with rice or pasta and let them hold it to practice using their hand and finger muscles. The noises which are made as your baby moves, shakes and even drops the container will delight and surprise them, and help them to understand consequences.

Bath time can also provide your baby with a chance to understand how they can affect things – as their hands and feet splash about, so does the water.

My daughter is 5 months old and I've been breastfeeding until now and switched over to formula milk. She has had no problem taking the bottle and until a week
ago she was sleeping through the night 7pm -6am in her own room/cot.
However this past week or so she is waking around 4am and taking 7oz of milk, then going back to sleep, but on waking she is only taking 2oz at 8am.
Any advice would be welcome, should I start weaning or not feed at 4am???

To Sam.grove... your daughter is probably having a growth spurt... When my son wakes up around 4 i give him some aired water rather than milk. An extra ounce of milk in there last bottle before bed usually works too.

funmade said...

my boy just turned 4 and is breast fed, he used to wake up twice in the night but now wakes up every two hrs before daybreak. He feeds a lot more often during the day too. He refused to take the bottle. Is this a sign that he needs weaning?

Nikkih01, my little girl is 4.5 months and always woke for a feed at around 4. I slowly cut that feed out and if she does now wake at 4 I leave her and she seems happy cooing and talking until she falls back to sleep. If he's not crying try leaving him for a little while to see if he drops back off to sleep without a feed. If he cries try soothing him by standing in the room with him or gently placing your hand on his tummy. It seemed to work for me.

Lisa, try putting the moses basket into the cot so he gets used to his room and his surroundings. I used a swaddle for my daughter too which seemed to help the transition from Moses basket to Cot.

my daughter is 12 wks old and is running out of room in her moses basket too so i've started using her big girl's cot for her daytime naps so she can get used to it and we have a nice chat or sing song when she wakes up so she learns it's a nice place to be! I've also started gettin her dried and dressed in there after her bath, touch wood, it seems to be going well so far! she still sleeps thru for around 11ish hrs tho in her basket so there's no immediate rush for the move...take small steps...i used to put Alannah in there while we listened to her fave music or played with her fave toy, just to get her used to the room...trial and error! good luck x

To sam.grove, how did you get your breastfed baby onto a bottle? I'mnot having any luck with my little girl? x x

POLAR1 said...

To mummy2anna - I struggled to get my breastfed baby onto a bottle and was at my wit's end as I had to return to work and thought she would starve. Then I tried a different teat and it was like magic - she took the bottle like a dream after 5 months of fighting it. She seemed to hate the Tommy Tippee Closer to Nature teats but loved Mam and Nuk. If you're still not winning, try offering a different teat and see if that works.

nsenel said...

My advice to everyone is go with the flow of your baby / child up until the age of a around 2 half years old . They are still so young and have very small stomachs when babys. So what if they wake during the night for milk. They obviously need it if they want it. Its tiring and draining doing night feeds but you just got to go with it. Babies change their routine so often your fighting a loosing battle trying to manipulate them into doing what you want. Every child is different work along side them not againts them. Babies and children will do different things in their own time when they are ready. Doing things this way wont make them spoilt brats but happy & content babys and children x

I just had my 1st baby 5months ago and its amazing. I breast fed for first month and half then tried expressing for a couple of weeks after, and then straight onto bottle. Princess is much happier on the bottle as she stays fuller for longer. I have already got her onto baby rice she loves it and gets very excited when its dinner time. She goes sleep around 10.30 all the way until 8.00 and doesn't wake up. I would advise anyone once u start giving formula always give water in between as they feel more thirsty and it settles them. My mother told me that we as adults feel thirsty in between meals.... so do babies

my little boy is 4months old and for the first four weeks i breastfed him. it was a great way to bond with him and although i enjoyed doing it, it was tiring, but i would definitely recommend it. when i introduced him to a bottle, it took him a while to get used to the difference but once he got there, he was great. he has only just starting taking a little bit of rusk with milk at bedtime but since 10weeks old he has been sleeping from 9pm right through til 9am :) cannot complain at all! happy baby = happy mummy

My son is coming up for 5 months, i was 100% sure that i was not going to put him in his cot untill he was 6mnts but he started to get aggitated in his basket. I ended up putting him in his cot just as he turned 3mnths and it was the best thing i did. To make me feel better i got one of those security cushion things ( its a piece of material with two rounded pads at each end) to stop him rolling.

kaydins mummy said...

i breastfeed but i started my son on rusks at 14 weeks because he was showing all the signs of wanting solids, also he started teething at 10 weeks and was always trying to eat everything.
when i gave him the rusk he loved them and still does he wakes up every morning at 9am for one and stays awake every night till 7pm until he has one and he is perfectly fine and healthy the only thing that happened was he was constipated for a while but was still a happy little boy

lynne battles said...

I have 3 boys and when I had my first boy I tried to breastfeed. Although I am classed as buxom I don't produce enough milk to feed my baby. I will never forget what my wonderful midwife said to me she told me not to beat myself up about not being able to breastfeed and to remember that my baby was and is the most important person here not me or my milk and to have tried and to have the courage to admit it wasn't working was better not just for baby but for me as well. I then put all my children onto Aptamil baby milk and they have all thrived!!!!! So it doesnt matter what you do just remember there is no shame in not being great at something from the start and it's better to admit defeat and to give the baby the best in whatever shape or form that is and that happy baby makes happy mum. My 3rd wee boy is only 22 weeks old and I have just started weaning him and my god is he a healty baby. I must admit I was very wary about leaving my baby till 6 months nearly to wean but he is absolutely wonderful and sooo happy. Just be open to all suggestions and then try and find what works for you and baby. There is no right or wrong way to parent as we are learning no matter how many kids we have. I hope this helps some mums out there who are being given advice that they feel they have to take it. Just remember no one knows your baby like you do.

Hi I have a son called Finley he is 4 months old, starting to wean him on puree's and he is also on Aptamil Comfort Milk. At the moment i give him his last feed at 9pm and the evening feed takes 1/2 hour to feed as he is very sleepy, i want to start puttinghim to bed at 8pm and wondered if you had any advice as he does seem unsettled at 6pm time. But usually sleeps from 9.30pm - 7.30pm.

My daughter is 4 months old, she has been sleeping through the night since she was 7 weeks old but for the past 2 weeks she has been waking up. We have been changing her nappy and then I am feeding her, she can fall asleep again in 10 minutes sometimes but will not go back to sleep unless she has had a feed. I have been putting her into her own room but she will not go back to sleep even if she has had a feed. Has anybody got any tips to help me out?

my baby is 16 weeks old tomorrow and we havent started weaning her, our hv told us to wait until she came out with the weaning pack(which she will then be 18 weeks) but she is showing great interest in our food when we are eating and she complains when i give her bottles during the day also she gets her last feed at 11.30pm but only take 3-4oz and goes straight to sleep, so we were thinking of giving her aptamil porridge and her milk at the 8pm feed to see if she will be mor content and sleep through, any advice wether we should try it?

My little son is now 21weeks. I have bottlefed him from birth and he started taking hungry milk from about 8weeks. He has been in his cot from 12 weeks and slept all night (9-9) since then! He take 4 8oz bottles a day and is thriving, he is so well behaved and content. After getting loads of advice at the start I decided to just 'go with the flow' he was fed on demand for the first few weeks but after a while got himself into a pattern! I think the hungry milk also helped to settle him at night! I'm looking forward to weaning in the next few weeks. I hope this may help some people :) xx

my baby is 4 and a half months and has just discovered that she can roll from her back onto her tummy, she can't however roll from her tummy onto her back yet - this worries me a little as she does this in her cot at night, while she is asleep and I am a little anxious as I know the safe sleep guidelines state that they should sleep on their backs, feet to foot - should I flip her back over when she does this or leave her to find her own way back over???
