This is seriously the answer to leaking overnight diapers.
These are the best things ever. They are diaper booster pads. Basically a pad with no lining on the back. I use them with pampers overnights, but with my first DS I used them with Huggies Overnights.
They are amaze balls. The only really place I can find them is babies r us.
