These are SO much better than Pull-Ups! I taught preschool (and potty trained) hundreds of kids over the years. In the beginning disposable training pants are great for at night and in a pinch (car rides, illness, out of the house) but then I'd switch to these ASAP. They are easier for the kids to use - no flaps on the sides or bunching elastic that gets worn out over the day. They are absorbent and have extra fill in the crotch to hold minor accidents.

The most important thing is that the child can tell when they've had an accident. The disposables absorb so well the children can't tell when they've gone, remember the cold sensation Pull-Ups? When they can tell they've gone they won't be sitting in urine/feces like I've heard concerns over, they'll want to use the bathroom/clean up. For a few dollars, these are worth a try!
