that is too funny!
We haven't had a leak here I remember the days of poo alllllll up the back and alllllll up the front in sposies!
Have you tried using woolies AND a pul cover for night? That is what I do sometimes (depends on the nappy) but we have a couple that last us ALL night (sandman and mirabai night nappy). I usually chuck a soaker over the top and just put him in his normal clothes. Haven't had a night leak yet and I don't change at night ever
