Before you had dc1 how much did you know about babies? I was talking to a friend who told me that she had read several books about pregnancy but had never thought to actually read about babies and children.
She had, had no experience of babies ie first of the friends to have a baby, no younger siblings/cousins, didn't babysit as a teen, so was really dropped in the deep end.
If and when I have children I will have several years experience of caring for babies/children and relevant training.
So what did you know?
