Baby Development Month 4

What to expect from your 4-month-old: tips on your baby's development, feeding, sleeping and playing.


Baby Development: What to Expect from Your 4 Month Old

One of the joys of your baby at 4 months is her increasing awareness of the world around her. That brings about other interesting development milestones too.


Growing and Developing

Your baby's arms and legs are likely to be a lot more active and stronger. She'll be able to hold a toy and shake it. You may notice her grabbing for your hair, your earrings or any nearby toys or objects. And it's likely that she'll try to put whatever she grasps in her mouth.

She'll push down when her feet are on a hard surface – or even your lap.

If she’s on her tummy she may be able to push up to her elbows and some babies even roll over at this stage. But remember all babies develop at different speeds – so you may have to wait a couple more months.

She'll be able to hold her head steady while sitting supported or being held. She may also turn her head to you when she hears you speak.

Your baby's vision has improved so she can see clearly across a room and can begin to distinguish some shades. She may now prefer primary colours.

She'll begin to babble and try to copy noises she hears – an early stage in speech development.

A few babies also begin teething – red patches on her gums and dribbling are among the signs. She might also keep putting her fist in her mouth. For teething tips, see our Guide to Teething.



Hopefully, you should be enjoying a good night's sleep as at this age babies can typically sleep 7 to 8 hours in a row. She's also likely to need a couple of naps during the day too – although she may fight it. Just settle her the same way as you do at night.



She's likely to be much more efficient at feeding now, so will need fewer feeds in total. Experts recommend not introducing solid food until 6 months old so if she’s hungry, try offering extra feeds. For more tips, see The Dos and Don'ts of Breastfeeding.


Caring for your 4 Month Old

As your baby is now putting objects her mouth make sure you don't leave small items within reach that she could choke on.

Remember to include some tummy time regularly to help strengthen her muscles.


Playing with Your Baby

Provide your baby with stimulation – she'll like different textured objects to explore. She'll also like you talking, making noises and singing to her – even if it’s not tuneful!


You this month

Hopefully, you’ll be getting more sleep at night now your baby is more awake during the day. She’s more fun too, with lots of smiles and giggles.

Remember to keep your energy levels up by eating regularly. Don’t skip meals because you haven’t found time to eat.
