Can you believe that in the space of just 40 weeks your baby will grow from the size of a grain of sherbet to a full wedding cake? Amazing, right?

As you move through your pregnancy , your little one will be growing and developing every single day, from their little limbs first developing, to growing hair inside the womb!

To help you visualise the exact size, length and weight of your baby each week, we've created this handy guide which will tell you exactly how your baby measures up to your favourite sweet treats each week - whether they're a little Freddo bar or a full tub of popcorn!

So, click through the gallery to watch your baby grow - and keep this page handy if you want to check back as you progress through your pregnancy. Plus, click the article link on each slide to find out more about how your baby's developing this week, and what you need to be prepared for.
