I'm going to be breastfeeding however, I will be returning to school soon so I'll pump and he'll bottle feed while I'm at school.
I have three 6oz bottles and three 9oz bottles.
Should that be enough since I don't plan on bottle feeding too often?
It should but once you go back to school you might be washing them daily depending on the kind of bottle.
I worked for 6-7 hours a day 4-5 days a week and my son was fed exclusively with my pumped milk during that time. I needed to have at least 22 4oz bottles in order for that to work and 25 made it alot easier.
