My LO has food allergies, diagnosed while breast fed.We've been super slow and conservative about introducing foods.So I know all about possible reactions.She can't tolerate sweet potatos for example.It's not an allergy, just an intolerance...
Soo,if your LO just started showing this symptoms, it could very well be food intolerances. How old is your LO?How long have these symptoms been present? You may need to pull all new foods and re-introduce them one by one. Otherwise it'll be hard to pinpoint the problem.You can start with the common offenders such as dairy and wheat and see what happens.
