Just recently Jacob has started to totally soak through his nappies overnight. When he wakes in the morning, his PJ's are wet or at least damp, and sometimes his sleeping bag!

We tried putting him into the next size up of nappies, as when this has happened in the past, despite him not being within the weight range they give, going up a size has solved the problem. The next size up fits just fine, but we're still having the same problem. He wears Huggies overnight and Snugglers during the day.

Does anyone have any suggestions?
