My LO is 12 weeks old. Since about 3 weeks, we've been using an all-in-one (Sunbaby) with a microfiber and hemp insert for nighttime needs. However, LO now sleeps for 6-8 hour stretches at night, and has recently gotten diaper rash on his butt and penis. I think it's from the ammonia in his pee, because his diaper is SOAKED by the time we change him. No leaks, just a very wet diaper.
Any tips on how to keep the moisture away from his skin at night? I'd like to avoid waking him to change his diaper. Avoiding disposables would be nice, too. I've heard fleece liners help, but I'm worried that he's soaking the diaper so thoroughly, the liner might just get soaked too.
