We have 23 month old twin boys who are on day 5 of potty training. We are using the methods in Toilet Training without Tantrums and they will not sit on the potty chairs very long (10 seconds max). We will be implementing a gated area off of our living room and putting 2 potty chairs in that area so we can do the gate and the potty bell and try to force them to sit by closing them in the gated area. We plan to put both boys in the gate with the 2 potties at the same time. Does this sound like the thing to do?
