We used Aldi in the day great for use in the day and have always used the pampers dry nites since she was tiny for bedtimes. Anyway now my daughter has decided she prefers to sleep on her tummy. The nappies don't leak but feel very damp around her front where her weight presses on it at night, she is already on 4+ but is 19lbs. Should I up a size again or will they just be too big for her. Any tips appreciated.
