We've been using Fluffles at night with no problem until about a month ago. He's starting getting leaks down his leg. It's not that he is weeing loads - often the nappy isn't that wet as it is early in the night - it seems to be more a problem with the fit. We use Bamboozles during the day but didn't feel they were absorbent enough for 11hours at night. Does anyone have any suggestions. DS is 15months, tall and skinny.
