40 Weeks Pregnant: Baby Size & What's Happening

At 40 weeks, the baby is about the size of a small pumpkin — roughly 51 cm (20.1 in), 3.4 kg (7 lb 8 oz). What's happening, and what the partner can do.

The date on the letter — and only a guide.

About the size of a small pumpkin — or a lamb, or a tiramisu. 51 cm (20.1 in), 3.4 kg (7 lb 8 oz).

What's happening this week. Any day now. The baby is ready — plump, strong, curled up and waiting for a signal only they know.

Ready for the outside. Kicks still count — keep noticing. Hospital bag by the door.

Labour usually begins within two weeks either side of today — the baby picks the day.

What your partner can do this week: Remember that due dates are estimates. Keep plans flexible and the mood calm. Go to the check-up with your partner if you can. Look after the practical things — food, washing, the phone — so your partner can rest.
