mmm not sure Christy? I know ours get a bit wet round the elastic in the thighs, but they dont really leak as such... however, they do sometimes leak when she does a massive watery poo, but those ones leak out of the sposies as well.. It comes out the top of the nappy though. She doesnt do nuggets yet though so cant comment on the nuggetainment yet! She doesnt have much meat on her thighs either, but at least the nappies arent loose around the thighs anymore. I still use the small peapods on the smallest snap setting.
