Ahhh little boys!!

They leak out the back because their penis would have been pointing up towards their belly when they wee'd. The wee then would have gone up towards their belly, trickled down and around their waist and back where there is no padding. Even if you point their penis down, with movements it can still move back up. But yeh just make sure you try and always point it down otherwise... thats the best you can do. I had the same problem with DS ALL the time. He would wet through every 2nd night. DD being a girl.. hasnt wet through once.
