thanks for the offer Annika - have Pm'd u I have a few WNSS in large but getting leg gape and leak issues! same with WNOS . The med UDSS didn't fit v well but not tried a L. I have bought a preloved coolababy to try as well.
UD did a medium long, fitted us up to PT, another vote for HH large PUL here, we have some Haute nappies (aussie brand) that were a much bigger BTP also, and our favourites were fuzzis, the medium fit from 7 months to PT at 25 months.
Hope you get on with coolababys, they are very good value and we've got 10 of them to go alongside my few wee notions. They work fine for us, my faves are wee notions though - we use large standard rise but I think normal rise would fit fine too.
