D is 5 months, probably about 16-17 pounds. We have had him on the 2nd snap on our BG Freetimes for the psat couple of months, and I think the size is still ok, though it is getting a little snug. Daycare is often undoing the snaps so that it is fully open. I feel like if we're fully opening the diaper at 5 months, how could he POSSIBLY fit in them till he's potty trained??? When did you open your CDs to the full size? Is my baby just a huge baby? WTH?

ETA: I'm talking about the rise snaps. We use aplix, so the width isn't an issue.
