I use either a regular (not premium) prefold or 2 joeys or 1 Joey and FB insert. I don't need 3 Joeys at night for my DD, she doesn't wet that much. It's not as trim as a disposable, but trimmer than my other nighttime solution, which is a ME Sandy with a Sandy liner and one Joey all topped off by a ME Airflow cover. Talk about a huge butt!!! :)
