I couldn't even find disposables to hold my 3 oldest. They would pee out of even the ones designed for nighttime halfway through the night. My third would even out pee an sbish with several doublers and wool. What we finally found that worked was a Thirsties hemp prefold wrapped around a flip trainer organic insert topped by a mother ease stay dry insert in a flip, pocket, or other cover. Bullet proof.
My fourth, strangely enough, is a fairly light nighttime wetter. It is a whole new ball game. I can put almost anything, except microfiber, on her and she is dry in the morning. I'm still getting used to it, but I'm not complaining!
Mom of 4!
