Your pregnancy: A week by week fetal development guide

(1 ratings)
Week by week fetus development
Having a baby is an amazing thing, and following your little one through their fetal development stages while you're pregnant is fascinating.

There's certainly lots to learn, so if you're interested in how your mini-me is growing then we've put together a guide to show you exactly how your baby is changing during their nine months inside your tummy.

From the first few weeks of fetal development, when your baby is technically a ball of cells, through their transformation to an embryo and right up until your little one's birth – this guide sees you through every week in confidence.

If you're having twins, we've included information on how they will develop, too, and the changes you can make to help give your baby (or babies!) the best possible support while they grow.

You'll learn all about how big your baby is growing during its fetal development stage, how much they weigh and all the things they're learning, too. There are some surprises along the way (like how early they get finger nails!) and some useful information on scans, check ups and appointments.
