We have 4, I love them. Because they have a pocket design you can add extra boosting and it really doesn't affect the fit (not with us anyway). I can easily get a p'tit dessous in there. It lasts through the night with that added even if it is soaked at times there are no leaks
I got a large. It fitted Rebekah prewashed so I'm hoping it still fits her after it's shrunk a bit! I didn't try it on Grace yet. I think it'll fit both of them though as they're only a pair of poppers apart on most nappies
Thanks. He's actually quite a skinny thing but his legs are still slightly chunky. He wears a M/L bedbug on the 2nd tightest waist and legs so I think this should be fine on him, if not he can just wear it big .
