Query: Frustrating, but a great size

My 2.5 year old is a big kid, 40 lbs, 38" tall. He needs a bigger potty chair, which this is. We have the smaller baby bjorn potty we were using but he can't keep his pee in it, he's just too big. I like that the potty cup comes out to wash, but it often sticks to his bottom as he stands up from it. We've had urine on the floor several times just because of this. I ask him to hold the white cup down when he stands up, he just gets over excited when he goes and stands up right away to look inside. He sat on one at a friends house that had a cover over the removable cup, which is by far a better design, but the high back on this one makes a nice spot for spending extended amounts of time on it as he reads and tries to go. All in all, I like it and would recommend it with reservations.
