Anyone else have a baby "failure to thrive"? My first kid was itty bitty. I was concerned because she weighed 20lbs when she was a year old. My old doctor told me she was fine, she's just little. With my second girl she's almost 6 months and she's 11lbs..only 1 percentile 😣 our new doctor is very concerned. She told me she is doing great everywhere else..just she fell off the growth curve in weight. My daughter isn't starved, she eats 6 oz bottles every few hours. She eats cereal and baby food but it has made her poop so hard that I've had to literally pick it out of her butt with a q-tip.

Doc told me to add extra formula and cereal to her bottles to add calories. She said come back in two weeks and if she's not having any improvement they want to do lab work.
