Hi, I have answered a similar question to this elsewhere tonight!!
You need to think about the things the child might do with the pot (being a bit off centre, knocking things)... think about how you would manage a scenario of the child doing damage to another child / herself... and consider what would happen if the pot came off or was broken (which should be following your emergency procedure).
I had a child with a pot a while ago and he managed just fine.
