🥒 25 weeks pregnant: your baby is about the size of a courgette

At 25 weeks pregnant, your baby is about the size of a courgette, adding softness while the lungs keep maturing. First-time mums usually have a 25 week appointment.

Baby is about 35 cm, 660 g

Your baby this week

Your baby is about the size of a courgette, roughly 34.6cm long and 660g. They are adding fat, so their skin is becoming smoother and plumper. The lungs keep maturing, and the nostrils are starting to open. Your baby's hands are busy, opening and closing, exploring their face and the cord. They respond to sound and touch, and may become more active when you are resting. Hair may be growing on their head, with its colour still developing.

You this week

You may notice more aches as your bump grows, especially in your back, hips and pelvis. Heartburn, constipation and haemorrhoids are common, and not something to be embarrassed about. You may feel breathless when climbing stairs. Some mums feel tingling or numbness in their hands, called carpal tunnel. Sleep can be harder. Let people help you where they can, even with small things.

Kind things to do this week

Questions to ask your midwife

When to call your midwife or maternity unit

If your baby's movements slow down, stop or feel different to their usual pattern, contact your maternity unit straight away, day or night. Do not wait until the next day, and do not rely on a home doppler. Also call your midwife or maternity unit if you have bleeding, fluid leaking, a severe headache, changes to your vision, or sudden swelling of your face, hands or feet.

Questions

What happens at the 25 week appointment?

Your midwife will check your blood pressure and urine, measure your bump, and listen to your baby's heartbeat if you would like.

Why do my hands tingle at 25 weeks pregnant?

Fluid can press on a nerve in your wrist, causing tingling or numbness, known as carpal tunnel. It usually eases after birth. Tell your midwife if it bothers you.
