24 Weeks Pregnant: What's Happening and One Thing to Set Up

Six months in, and the bump is hard to miss now. Around this point a lot of parents notice the pregnancy taking up more room, both physically and in the daily planning that's starting to pile up.

At 24 weeks, your baby is roughly the size of a corn on the cob, around 30cm from head to heel.¹

What's happening at 24 weeks

This week marks a milestone doctors call viability. From 24 weeks, a baby born early could survive with the right care in a neonatal unit.¹ It's a quiet, reassuring marker of how far things have come, even though most babies stay put for many more weeks.

The baby keeps growing steadily from here, putting on length and starting to fill out.

What's common around week 24

Many people feel new aches as the body stretches to make room. The ribs, back, breasts, and stomach are common spots for that stretched, achy feeling around now.¹

These aches tend to come and go with movement and position. Your midwife or doctor is the right person to ask if anything feels off or you want reassurance.

Start a pediatrician shortlist this week

Here's a small admin task that's easy to knock out while you still have energy: jot down a few pediatricians to call after birth. Ask friends with kids, check who's in-network, and note a couple of names and numbers.

It's a five-minute list now that saves a scramble later. You won't need to choose today, just have options ready.

This is also a good week to set up nappi if you haven't yet. The baby profile you create now, with the due date in place, becomes the baby's tracker the day they arrive. Same record, same app, no starting over. You can read more in our resources on what comes after birth.
