ATM I'm trying out a few AIOs to see which suit DS the best. I picked up an Itti Bitti dlish snap in one in a small (in the 'like a tiger' design - OMG so cute!!!).

Hes almost 12 weeks old and approx 5.5kg. He's a skinny minny too. Narrow around hips and thighs IYKWIM? '

Tried the small on him, and its a bit too tight on the smallest snaps, let it out to the last snaps and it seems OK around the tum / waist, but when he stretches and kicks his legs out it sort of rides down.....almost to the point where its hardly even covering his bits! I wondered if medium might be the go?? Also seems a little bit gapey around the legs - poo containment concern there...hmmmm.

Any thoughts and suggestions would be great....loving the IBs and would like to get more.
