Good training potty for a very small but ready toddler

Kelsey

My youngest is showing an interest in the potty so I'm thinking about getting her started. She was a preemie and is still small enough that a regular kids potty seat on the toilet and other training potty chairs I've seen in stores are too big- as in she can easily fall in if she goes on it by herself.

Are there any smaller seats that anyone knows of that might be worth checking out? Must be available in Canada
