Re: Amonia Smell
Do your diapers have any build-up?? What kind of detergent are you using?
I would try stripping your diapers and inserts (if you use pockets) if you haven't already. Usually that's the problem. Also, you can boil hemp, and prefolds, etc. to get rid of extra build-up/smell.
I use Sun deterget and the Sun version of Oxyclean (to help strip inserts). I have had awesome luck with that.
