So if you are born with all the eggs that you will use to make your babies. Then your children were kind of in your mums stomach when she was pregnant with you.
Which also means that the egg that your from was in your nans wombs when your mum was growing, which means that the egg used to make you has been around a lot longer than you. ( I was born in the 90's but my egg was in my Mum who was in my nan during the 60's).
Yes, I am sleep deprived and looking at a newborn.
