Some of you asked me the same questions so here are some answers.
She was low weight when I took her to the doc and the doc said the same thing. She is 2 monthes. She would do this thing where she would suck for a long time like 1 hour or more but I was dry after like 10 minutes on each breast and she would still ask for more.I know because I wear a nipple shield and no milk was coming out of it ans so I would give her formula and she would be satisfied. I dont know how many poopy diapers/wet diapers she had on just my milk.
