@Mikaela how did you find out what was causing your babies eczema. My little one has eczema and we are trying to figure out what is causing it
@Tiffany we didn't until she started solids and her eczema got significantly worse after a few weeks. We then removed the few major allergens from her diet that we'd tried, then reintroduced them again and discovered it was egg!
Colic can have several non-allergy-related causes such as reflux, tongue ties, body tension issues. Occasional loose stools can be normal, and so can eczema, but they can also be signs of a different allergy. Mine is CMPA but doesn't get eczema from it, but does have an egg allergy which does cause eczema.
