Your 3 month old – baby development guide

Baby Development Guide - three months old

What a fun month this will be! Your baby is turning into quite the little character. At this age, babies usually have been smiling for a while now but soon they will add laughing or maybe even squealing with delight to the list of things they can do.

Your baby is enjoying life at the moment. At three months, babies are growing more interested in the world around them but, thankfully for you, they are still relatively immobile! What a great age!

How is baby going?

Your baby is also gaining more control over their body – which means they’ll be more of a handful when it comes to changing nappies and getting dressed. There’s just too much else going on to stay still for that long. Your baby probably won’t be content to lie on their back anymore. They’ll want to be propped up so she can watch the world go by.

This month, your baby is starting to gain more control over his body and starting to realise that it is, in fact, their own body. Your baby will reach for toys and might enjoy bearing some weight on their legs while ‘standing’ with support on your lap. Try playing peekaboo with your baby or sit and read them a short book to. Make sure you buy toys that are safe for babies – because they are going straight into their mouth. Stuffed animals look cute but you should check for loose button eyes, strings, bows or stray wires.


Vaccinations are due when your baby is four months old. Make an appointment with your GP or your local immunisation clinic.

How are you going?

Now the dust has settled you might want to make time to focus on yourself and on your partner. Almost without exception couples will experience some relationship issues after the birth of a baby – particularly if it is their first.

With so much focus on the baby – sleeping, feeding, clothing, bathing, settling, transporting – couples often get distracted from focusing on each other.

It is an emotional ride for new mothers and new fathers and it is worth getting some tips on maintaining a happy and healthy relationship after baby.
