So I have a 6 month old. In all that time dh has never taken the initiative and changed a nappy. Even immediately post section I had to ask him. On the whole I have got on with it as I don't want to seem a nag. Anyway sunday morning dd was in the bed with me (cosleep some of the time). She had done a leaky poo which needed changing iimmediately. Before noticing I had mentioned that my back was killing me. It does 1st thing most mornings. I than moved dd and noticed the poo. So I commented on the fact she was dirty.
Dh didn't offer to change her so I had to ask him.
