let her know you're thre to help a much as is needed. but don't be too pushy, like a miss know it all. It i her child, and doesn't want to be told what to do. As the baby gets older, again it's her's to discipline, don't interrupt too much. Don't undermine her is what I'm trying to ay. Let her know you were a delivery nurse, and see what she wants from there. good luck and congratulations.
