One size doesn't fit all

My parents are in a quandary. I'm a growing toddler and they can't seem to get the correct diaper sizing for me. I've been using Drypers since year 1. It seems that their XLarge size is too tight for me and their XXLarge is a bit loose. Other brands are nearly offsized for me. My parents are now trying different brands and sizes to see whether they suit me. If you asked me, I prefer to go nekkid .... heheheheh
