Breastfeeding & Going Back to Work

Hi ladies I have some questions for those mommas who breastfeed but are working as well. My son is 2 weeks old today & I am going to wait until he is about a month old to go to work. I will be working night shifts from 7pm-3:30am. My fiancé will be at home with baby & will be feeding him, etc. I plan to breastfeed him during the daytime when I am with him & he will only be bottle fed when I am at work.
