I'm looking for input from anyone who may have experienced what I'm going through right now with my son. He's 18 mos. old and is 22 lbs. He hasn't really gained weight for the last 5 months and our pediatrician is concerned. He has food allergies (milk, eggs, nuts). I'm still nursing him and he doesn't appear to be ready to wean yet, which I am fine with. He's taking Cytra-3 because he had low co2 levels and they are back to normal now. We saw a nutritionist who said he's fine...no need to worry. The next day we had a GI consult and they said it's failure to thrive. They tested his stool and said that there's no evidence of malnourishment, but they want me to stop breastfeeding immediately and start feeding him higher fat foods. I'm worried sick and am having a hard time with 2 completely different diagnosis. I can do the fatty foods, but he went on a liquid strike when I tried to stop nursing and I'm guessing that breastmilk is better than dehydration. He will drink water from a sippy cup, but he's not impressed with soy milk. Any thoughts? Advice??
