Your Baby Week By Week
Those first few weeks with your newborn baby can be both overwhelming and exhausting – how should your baby be developing both cognitively and physically each week, and what are the common problems to look out for? To help ease you into your new journey, we’ve broken your baby’s development down week by week, from the milestones they will hit, to how much they should be eating and sleeping.

-
Week 1
Week 1 with a new baby: “Take it easy whenever you can”
Your tiny newborn might be a little wrinkled and squashed, but they'll be learning how to live in the world. They'll also be sleeping for up to 17 hours a day. -
Week 2
Week 2 with a new baby: "17 hour sleeps and venturing outside"
Your baby may still be losing weight as they're not used to feeding yet, however this will soon stop. Take a look at their nails - they'll probably need a trim! -
Week 3
3 week old baby development
Your baby's nervous system and muscle control is yet to mature, so you’ll find their movements to be jerky. Their skin should be peeling less this week. -
Week 4
Your 4-week-old baby’s development
As your baby reaches one month old, their hearing will be fully developed and their vision is improving. Your baby might still be a little cross eyed this week. -
Week 5
Baby milestones: 5-week-old baby development
Get ready for the growth spurt! Babies will normally gain around 200 grams this week, so expect a hungrier baby and more nappy changes! -
Week 6
6 week old baby development
It's time for tummy time! Your baby might be able to lift their head this week, as their neck muscles develop. Their memory and hearing is also improving. -
Week 7
7 week old baby development
Your baby has grown almost two inches since birth and is starting to look more like a little person. They're likely to start using their limbs more this week. -
Week 8
-
Week 9
9 week old baby development
As your baby starts to outgrow their moses basket and smile for the first time, that tiny newborn you brought home nine weeks ago has changed in so many ways. -
Week 10
10 Week Old Baby Development
As your baby starts to fill out more, they'll start to realise they can use their arms and hands, meaning they'll be lots of grabbing at things this week. -
Week 11
What can you expect when your baby is 11 weeks old?
As your baby starts kicking and punching, you'll notice they have more control. Now is a good time to prepare for that first immunisation appointment. -
Week 12
Your 12-week-old baby’s development
This week your baby will get their first set of jabs. You're also in for another growth spurt, which means crankiness, restlessness and a hungrier baby.
