The best night nappy i have found is the GK ANY TIME with an extra booster. my dd is a heavy wetter and these have only ever leaked once and she wears a GK every night for bed!

I could boost a BG and it would work i think!

Itti;s are not made for night, so i wouldnt trust them...they are releasing a night nappy soon! (but im told it will need a cover!)

ive heard sandman is good too but i dont have any so cant comment there.
