My 3 week and 6 day old is constantly feeding, all day all night and I often don't get much of a chance to refill (once I do he gets his feed and goes back to sleep). I know he's getting my supply up but it's not very fun. Can anyone recommend a formula to top him up, I'm not planning on using all the time, I'm just wanting something to save my sanity. Also, as a baby that only had a poo every second day, something that won't block him up! Please help.
