All our night nappies leave a massive leg gape. I used to just put up with this but it's really starting to bother me now. WNNN gape is terrible - starts off not too bad but by morning it's all wee-soaked and has sagged. UDNNs are the same apart from the old-style mediums which fit well. In terms of new-style M too small, L too big. Have also tried FFNNs which at the time didn't leg gape, can't really remember why I sold them.... and HLBBs which I don't like.
Any advice much appreciated.
