practical:
Change for car park(stressed pregnant lady shouting 'I don't want to get a bloody parking ticket'!!!)
it may be boring and longwinded until the big push happens. Each person is different, however,if DH had complained he was bored, or started playing with his phone, I would have killed him.
Be prepared to act like a servant, and be shouted at (rub my back, no, nt like that, that;stoo hard, that's not right.. where are my slippers, etc...)
pack treats anddrinks, have phones charged for the very exciting phone calls when baby has arrived, and ensure camera charged
afterwards, when youget home, be prepared to have to politely/ firmly declinevisits if its nota good time, and limit over enthusiastic granparents on both sides
Good luck, hope it's a happy birth
