I've just bought some second hand tots bots easy fit nappies. I've just tried one and it's leaked. The pad inside is wet but not drenched, but when you look at the outside you can see a wet area over the front, where it looks like the moisture has just soaked right through. Does this mean the pul lining has gone and that essentially this nappy is no longer waterproof? I've looked at the inside and can't see obvious delamination but then sometimes you can't see the tiny holes. What do you think, is this just useless? I'm starting to think that buying preloved is not such a money saver after all.
