DD is PT but wears a pull up overnight still (occasionally has a dry night, not usually though). Anyway, 2 nights in a row she has leaked out of the back of the waist of the pull up (and gotten her jammie top all wet). This has never happened before. If she wets the bed it's from leakage below, not above. Anyone experienced this with the overnight pullups? Do I go a size bigger or what? Is there a size bigger-I can't remember as DS is in the larger underjam things which I are way to big for DD.
