Thanks MrsD.
I really thought it was the one bowl of saurkraut that I ate, many months ago. Then later I thought it was eggs and cut them out of my diet.
The pimples did get better (on his cheeks and doesn't look dried out like excema tends to look) but are still not gone.
Actually just this afternoon I gave him some banana pudding (homemade, of course
). This will be his first, first-hand contact with eggs... so we'll see what his cheeks do.
I appreciate the list of foods. I wasn't eating nuts for a while (I generally don't eat them through the summer) but with the cold weather coming, I always get the gumption for some nut dishes... so I don't think it's them.
You've given me loads to think about.
Thanks again.
