Quoting ☮Sugar Magnolia:" <blockquote><b>Quoting 3.24.10 ♥ 9.10.11:</b>" Mine is too How long did it ... [snip!] ... was even worse when she was on milk/soy formula. So she gained weight super slow and was just miserable when she had to poop "
We fortunately caught it pretty quickly, but only because she was vomiting after every feeding, then one day she just stopped eating. Ate like 1 ounce in a 24 hour period. We took her to the hospital and they tried telling us it was only reflux
Her pedi listened to us though and we tried several formulas, and she finally suggested Alimentum and it was almost an immediate difference. She was still diagnosed with Failure to Thrive though, even on the alimentum she barely gains weight.
