Little Gertie is preoccupied with all the things that Gilby does that she used to do when she was a baby. She is fascinated by breast-feeding and acknowledges sagely that this is the way she used to get her milk. (She also likes to hitch her dress up to feed her doll when we are out and about, but that is another story.)
All the toys and equipment that have come down from the loft for Gilby she knows that she used to use, and even if we have bought something new we have to pretend that it was hers first.
She also loved the idea of my 'baby tummy', and because some of the other mums at nursery are also expecting or have just had babies, this idea is being reinforced all the time. So she is aware that she too came from my tummy, and confidently pronounced that it 'tickled' when she came out of there. Well, if that is what she would like to believe...
But I did have to put my foot down when Gertie and Gilby were having a bath together a little while ago and she pointed to a certain part of his anatomy. "Mummy, I used to have a willy when I was a little baby, didn't I?"
