My baby will be 3 weeks old in two days and I've been exclusively breastfeeding her. I'll have to return to work in 9 weeks and we'd like to start introducing the bottle in a week or two. When I return to work she'll have to take a bottle, but I would still like to breastfeed her as well. I was hoping to get advice on how often I should pump, how much milk I should produce to store in one sitting/length of pumping session, how best to store the milk in the freezer, etc as well as just general advice to help prepare for me going back to work. I'm not sure how much milk I'll need saved up or how much milk in ounces she actually will be drinking in one feeding. Any advice would be so greatly appreciated!!
