So I finally found an overnight solution that works consistently: BG 4.0 with a microfiber insert and a charcoal bamboo insert. Yay!
Most nights his overnight diaper smells like strong urine. I figure this is normal. That's a lot of urine in there. Well this morning it smelled like strong ammonia. Yuck.
Is this also normal? Maybe he ate something that made his urine stronger? It was a new diaper (prepped) but with inserts I've used maybe 3-5 times before.
