We have a mixture of prefolds/covers and pockets... a few fitteds. They all get washed the same. We have FB medium pockets we use at night and seriously, they reek!!! I always thought it was just because they were on the kids for 12+ hours every night (I mean, I knew they wouldn't smell good after that!) but last night my little one had a middle of the night meltdown so I changed his diaper in case that was his issue, and I was holding him when he peed in it and it smelled like ammonia right away!!! What gives and what can I do to fix it??
