DS has been EBF for almost 6 months now and today we tried him on a bottle of formula, which he gulped down. Tonight I noticed a pinprick type rash on his torso (no raised bumps) and some hive-type spots around his arm, neck and thigh.
Is this likely a reaction to the formula? He hasn't had any other signs of a CMPI, seems happy. I'll take him to the GP if it's worse tomorrow but just wanted to know if anyone else experienced this when they introduced formula. Do their bodies just need to adjust to the change or is this probably a sign of an intolerance or allergy?
