Baby is 2 weeks old today. She has had problems latching so she's been fed pumped milk from a bottle since the beginning and an occasional formula bottle if I don't pump enough. She's been getting 3oz every 3 hours. Pumping 2-3oz per session also every 3 hours. Anyway I bought nipple shield yesterday and she seemed to take to it. Just want to know, how long do you keep her on each breast? When do you know to switch? Or do you just let them go until they stop and then switch? Do you just do 1 side then the other then stop or keep going back and forth until they're satisfied? And do I try to pump after she's done? Just trying to get it right.
