I had my daughter 10 days ago and we have been exclusively breastfeeding. everything is going great, but my doctor told me I need to pump the side that I'm not nursing on ( she falls asleep at the boob) and store it (which I am not against), he also told me to introduce a bottle before 3 weeks or she won't take it??? I wasn't planning on introducing it to her until at least 1-2 months. what are your opinions as nursing mothers?
