Anna I haven't been too happy with the newborn magicalls but I find the smalls to be fine. I think it's because there isn't much of a soaker in them. Ruby is 3.6ish kilos and the small is a tad big on her but not for much longer I reccon.
I haven't got the newer haute pocket but had an older style one. It was fine on my broad little fella but he ended up being too big in the rise for it, though there was plenty of room around the middle.

Gigi from my observations there are narrow crotched nappies and there are nappies that are narrow in the crotch and the seat if that makes sense. Ittis are narrow in the crotch but have a wider seat than swaddlebees for example which is why I could use ittis but not sb's on Caleb
for you too hun!

Rhoda there are a couple of nappies that shorten down to CT so tell us in longhand

WORB: itti bitti boo and maz cover
WOCB: air!
