These are averages. Every baby grows at their own pace.

How the baby is getting ready

The baby's eyes can now focus, and their vision keeps developing. [1]

How your body may feel

Sleep may be hard, and some people have vivid or upsetting dreams. Stairs may leave you out of breath. [1]

Everyone's pregnancy is different. If something worries you, call your midwife or doctor.

Worth doing now

If you haven't had the whooping cough vaccine, ask for it before week 33. [1]

Questions

What if the baby's movements change?

The NHS says to call your midwife or maternity unit straight away if the baby is moving less than usual or the pattern changes. Don't wait until the next day, even in the middle of the night.

Do movements slow down near the end?

They shouldn't. The NHS says you should feel your baby move right up to and during labor. There's no set number of kicks to count: get to know your baby's usual pattern.

Is my baby exactly this size?

Probably not exactly. The length is the average the NHS gives for this week, and the weight is the middle value (50th percentile) of the WHO fetal growth charts. Your scan results are the ones that count.
