I didn't want to have to buy two. The plan worked until the first day I was potty training when they had to go at the same time and one of the boys peed on the floor while waiting. We had two and it worked so much better.
We haven't gotten to that point yet, but I will because a friend (of a singleton) passed on two that she (well, her son) never really used!

I just bought two. I haven't started potty training them yet but I thought it would be a lot easier to have that second one. I can always keep it on in the upstairs bathroom and the other one downstairs.
Re: Do you have a potty for each child?
We had two potty chairs. It made peeing first thing in the morning easier since they both had to go.
