So I am 9 days away from returning to work, and trying to figure out how the first day is going to go. I think I probably have 50-60 oz in the freezer, and am going to start pumping twice a day after baby nurses to increase that and increase supply. How do I know how much to leave in a bottle for him? I've heard 1-1.5 oz per hour, but is that true for all ages of babies? Any other advice for first day back? First day back is a Saturday, so he'll be home with my husband. Then starting on Monday my mom will watch him for the week.
