Hi Alice, I can't say for sure whether it is a dairy intolerance but I do know for sure that your baby can gain weight and still be MSPI. My baby girl has a severe dairy intolerance (bloody stools w/ the smallest offense) and has progressively gained weight all along. :wink:
Is their stringy mucous along with the loose stools? Check very carefully for blood too. Sometimes you are unable to detect blood with the naked eye but if you suspect it you can take a diaper in to your clinic and they can do a simple test to determine for sure.
My dd's stools cleared up with in 24 hours of taking dairy out of my diet. I mainly bf but we also supplement after her last bf with the hypoallergenic formula. It has worked nicely for us but it tastes awful and makes for very stinky poops. :roll:
Although eczema is often related to food allergies it doesn't always clear up when the allergen is removed. You may still need to treat the eczema with a really good cream (ex: cetaphil, eucerine, aquaphor) a few times per day.
Good luck and keep us updated.
