Pros: Size, portability, design, ease of clean-up
Cons: Discontinued, no non-slip
I use this potty for my 9 month old daughter (we practice elimination communication), and it is our favorite. She has been able to sit on it comfortably since around 4-5 months old, and I think it will work for a long time to come. It is compact so I can take it to the car when we go out. My favorite aspect of this potty is that when my daughter sits on it, she is in a squat rather than just sitting on a chair with a hole. Only downside is that it has no non-slip surface on the bottom, so it slides around the bathroom floor.
I would purchase more if they hadn't been discontinued!
