Something really random has started happening while my baby is feeding. He's formula fed and feeds very well. He has suffered with reflux. But we've controlled it with Infant Gaviscon. Otherwise seems happy. Gaining weight etc. He's had baby acne for a while. Now, but is clearing. Anyway, when he's been taking his bottles. A blotchy red look rash comes over his face and his chest. But as soon as the bottle is finished. A few minutes later it's gone. It doesn't seem to bother him. I just want to know if anyone else's baby has this and do they know what it is??
