Thus is my second child and first time BF so I am nearly clueless about it. I will state everything that's going on so hopefully someone will be able to comment.
After birth we were giving my daughter formula. (we thought she was tongue tied like my first born and I refused to go through that again. I had a week from hell and so did my nipples trying to breast feed a severely tongue tied baby) however, after the lactation specialist visited our baby we realized her tongue Tie was not as severe and a nipple shield allowed me to BF fairly easy.
I have noticed the past two days that my NB was getting gassy and a bit fussy after feedings. It has gradually gotten worse. She would feed for an hour and still seem unsatisfied .... Now she will be crying, having stomach pain etc. after feedings. It will take at least 1 hour to console her 7 /10 times. She then started to throw up, a little at first and then a huge amount two feedings later. She has had substantial wet diapers, but no good poops. She will fart really loud and there will be a small amount of poop in her diaper. I am not on special diet, I've been eating normally since BF. She is just in so much pain after feeding ... I think she's constipated ... I also don't understand his she could throw up so much ... Thanks for any help!!
