Share this article with other mums

The first year of a newborn's life is one of the fastest in human development, so what exactly can your tiny 3-month-old baby do now?

Month 3 baby milestone

Once your baby turns 3 months old, he will no longer be considered a newborn and is now called an infant.

According to the World Health Organisation (WHO), during your neonate’s first 28 days of life, he is at the highest risk of not surviving, so it is extremely crucial that he is provided with appropriate feeding and care during this newborn stage.

Even though your little one has graduated to the next level and he still has a lot to learn, you’ll be amazed by his growth and development so far.

Physical development of a 3 month old baby

Upper-body strength

Your 3-month-old should be gaining more strength in his neck muscles and during tummy time (or when he is placed lying down on his front) he should be able to support his head and chest with his arms.

Lower-body strength

When your infant is lying on his tummy, you might also observe that he is able to stretch out his legs and kick, as he begins to gain more lower-body strength.

Neck strength and control

Your baby’s neck strength is noticeably improving by now and when you hold him upright, you will see that there is almost no more head wobbling.

Hand eye coordination

Your infant can now start to open and close his hands, bring them together together, and take a swipe at bright-coloured dangling toys in front of him as he begins to explore with his hands.

Hand to mouth

He can now grab a toy in his hands and move it straight to his mouth, or he will bring his hands to his mouth – so remember to give him baby-safe toys which are age appropriate and has no small parts which may accidentally be swallowed or is a choking hazard.


By 3 months, your bub may start to be able to roll onto his tummy when he is placed on his back – so be careful when you are changing his diaper or if you are playing with him on your bed.

At this stage, your infant is becoming more aware of the things around him and he will be interested to touch and feel different textures.


You will notice that your baby will turn his head and smile at the sound of your voice and he will also start to show his love of listening to all kinds of music!


If you look at your baby, he will maintain eye contact by staring right back into your eyes and he will also enjoy gazing intently at his own reflection in the mirror.

When your infant bats at a dangling toy and it moves, he will start to understand the basics of cause and effect in things and his brain will make thousands of connections as he concentrates on this new skill.

Your infant’s eyes should be working together to move and focus, especially when something is moving in front of him – such as a toy or your hand.

Social smiles

Your baby’s sweet smile is no longer exclusively reserved for just mummy and daddy now and he will begin to be more generous with his grins with anyone who flashes him a smile first.

Being friendly

Your bub might be starting to get fascinated by other babies around him, or even his own reflection in the mirror.

Understanding emotions

At 3 months, your little one is trying to understand emotions and communication so is starting to link what you are saying to your facial expressions.
