Changing table question

So our crib has an attached changing table which can only fit a pad sized 16 X 28. However, every pad out there seems to be 16.5 X 33. Anyone else had this problem? And, what'd you do?

Try a bassinet mattress, rectangle 15x30. I got one at burlington coat factory, or you can order something different online but pay shipping, It may fit if you squi**** in there. If nothing else, take a standard contored pad and cut 5 inches off. Tip, get a queen sized watterproof zippered pillowcase cover and slip it in there.

Thanks, hadn't thought of the bassinet mattress
