Ieckert, I haven't been in here for ages but thought I'd pop in to say that my DS is doing the same thing! He kicks up such a stink if I put an IB on him. I really do think they squash his boy bits. I tried the only DM I have and he wasn't happy with that either. Sooo, he is in sposies all the time now!

So they lack ball space? hmm, I might have to mention that to my sister because she uses them on her child. My nephew is on the larger side of the charts height/weight wise so might run out of space soon.

Leckert-I was looking at an Abby Gro on Pixie the other day and realised they'd suit a boy pretty well. They're OSFM and you can get the PUL basics for $25 each. Snap in inserts with additional booster. Pixie is lean and I still have the tabs snapped without any space between them at 2 yo. the inserts are concaved between the legs after I take it off. Maybe give one of those a try? Pixie loves her AGs

ETA: sorry did you mean the velcro like GK or the sizing? AG are all snaps and a very diverse fit.
