We are currently having the same issue but only at night. I've finally gave in and have been putting her in a sposie at night.
hi,
we were having the same problem at night, and have gone to a motherease bamboo one size with a thirsties wrap or motherease wrap or any wrap really! This works really well, i put the bamboo motherease booster in, folded at the front and we really rarely get a leak now.
As for during the day I mainly use flips staydry, or wonderoo v2. The v2 seems to fit really well on my LO's skinny legs, and I only use the bamboo insert, not the microfibre ones. The bonus of the wonderoo v2 is that they do minky pretties, which are great.
