I've been on Vacation for a week and been breastfeeding my son exclusively no bottles. Well I go back to work tomorrow and my son refuses to take a bottle. My SO who watches him during the day also got him on a schedule of sleeping during the day and up at night so I'm up because he is refusing the bottle I don't know what to do .
