We're starting to think about potty training too, and friends have also recommended potty chairs. I've just ordered a Tippitoes 3-in-1 potty/toilet trainer seat/step from Amazon, so we'll see how we get on with that! I also liked the look of the BabyBjorn ones but they were a little expensive. The potty chairs, being higher, definitely look more comfortable than squatting down so low on a regular one.
