I got fluffy mail today and in it was IB SIOs for #3. The inserts in the SIOs seem to not go together very well - whichever insert is on the bottom can't lie flat because its too long to fit nicely under where the top insert snaps in ITMS.

Do they shrink when I wash them, and then fit nicely? They way they are at the moment makes it look as if there is going to be a little bulge either at the front of the back, which I think would be uncomfortable for bubs. I got the SIOs cos I figured they will dry more quickly than the AIOs, but if its a problem I'd rather see if I can send them back now before I wash them and swap them for AIOs instead.

Thanks.
