DS1 has had a rash like that 2 times, and always related to teeth!!!!

I just smothered him at every nappy change with sudocream and changed him at least 3 hrly during day, if not earlier. He wouldnt sit in bath at all, and screamed during nappy change, i used warm water and a cloth to clean bum.

Nappy free time helped a bit too but hard to do when he roams all over house etc.

Hope he is better soon.
