I've been having problems nursing my 3mo daughter. She's my second child that i've nursed. She's about 14lbs and peeing wonderfully. She has strange poops, in my opinion. Her poops are brown with thick pieces in it. She gets very fussy before nap times and it's hard to get her to sleep. Another thing I've noticed in the past few weeks is that she makes a clicking noise sometimes while nursing. I've noticed that this is starting to get to be a problem because she lets out a big burp after a nursing. I discovered that I had forceful letdown about 1.5 months ago because she was gagging/choking during letdown. I blocked nursed for about a week and it has seemed to clear up that problem. How can I solve this clicking sound problem? Anyone have had this happen to them?
