congratulations!
of course these are the essentials.......but most of the mothers will pre-pack one big bag when they suddenly find that their babies are soon to come out and need to go to hospital straight away. this bag contains:-
a. pajamas and slippers (some mothers prefer personal things)
b. toothbrush, toothpaste, towel
c. some diapers (some hospital may ask you to prepare)
d. napkins for mothers after delivery (can buy from supermarkets)
e. other stuff that can be used when staying in hospital.
remember, babies could come out at 7 months.
and most important! shop the necessities with your wife, showing how committed you are to the new family member and how much you love her.
