I have been using maths to countdown the weeks to when my new baby cousin will be born. My auntie hopes the baby will stay in her tummy for 40 weeks. Every week we count up how long the baby has been in her tummy and then work out how long is left by taking that number away from 40. She is now 38 weeks and I'm so excited because 40 subtract 38 is 2 and that means only 2 weeks (hopefully) until I meet my new cousin!
