Hi clothies

just need some advice regarding a major heavy wetter, ive resorted to sposies for playgroup and out and abouts because Lilee just pees through everything, I need the best Trim nappy that is for heavy wetters what have other people used successfully???
I use wool covers with 16 ply boosters, and have tried the following nappies with no success...
plain fitted towelling one
funkybumz
happy heiny pockets (stuffed with bamboo fold ups)
baby beehinds with extra boosters
she pees through all of them and she has gorgeous meaty thighs

so they have to be bigger, I find the AIOs leak out the legs, also pul covers wick out the leg,
Its ok at home because I change her constantly, but I need something for playgroup, that will last 2 hours and still allow her to climb and play.
Im happy to spend money on it as chett will use it later also but Im sick of buying things that dont work....
thanks for reading
my apologies if this isnt the right forum I wasnt sure
