Sorry I am sure this has been discussed lots of times.
My 3 yr old dd asked me today and wouldn't leave the subject alone. I said that mummy and daddy have a "special cuddle" and then a baby grows in mummy's tummy. She wants more info about the special cuddle. I am not sure what to say that is appropriate for her age but she's not going to let this one go. Any advice please? And any books on the subject that could help?
