I have two little skinny-minis, ages 1 and 4, and got a Dapper Snapper for each of them.  I love them!  Finally a way to hoist up those pants that don't have adjustable-waist elastic, and so much better than the belts and suspenders that I was using previously.  These are great and don't get in the way of diaper changes or using the toilet.  Such a simple invention, but genius!
