When I first saw this post title, I was going to say YES YES YES, but then I read it.
My little one gets a really bad rash on his cheeks with oats. It is really hot to touch, has blisters, it is awful.
How bad is the red ring around his butt? That can sometimes be the only sign of an allergy, but it can also be from trying to poop or to much acid in the poop.
Is he fussy or has his mood changed any?
If it were me, I would try rice cereal first. That normally is a more gentle one for babies first cereal.
