So every now and then I'll notice DS's lower back is wet. Last night he woke up crying and this seemed to be the reason because I changed his pjs and he went back to sleep. It's not pee cuz it doesn't smell and we change his diaper frequently. I don't see why he'd be sweating, we keep it at 70 degrees and he wears a onsie and pjs or pants during the day, no blanket at night(he doesn't like them) he has reflux so I don't know if he spits up and it ends up down his back. I'm At a loss, thoughts?
