My stash is mostly Indian prefolds and a few pockets for nights. The ammonia is killing me! DD woke up with a blistered bum! She was in a HH stuffed with a hemp baby bigger weeds. I am washing in Sun detergent and then doing a complete hot/cold wash cycle with nothing. Where is the ammonia coming from? I have not had this problem in a year and suddenly I can't fix it. DD is in sposies and slathered with desitin. Help!
