H.S.
While I haven't had to potty train my child yet I can give you some tips that my friends have tried with their children and that my mom tried with me. Let them decorate to potty with those cling window stickers or regular stickers (and use GOO GONE later to get them off) so that the potty looks more inviting to them and they'll want to use it. Try putting a closeable jar of their favorite candy on the back of the toilet (hopefully where they can't reach it) and have them sit on the potty and try to go, then after give them a piece as a reward for at least trying and hopefully one of the times they will actually go or start sitting on it by themselves. Last thing I can think of is anytime you go potty make them come with you so they see what the potty is for. Good luck I hope these help!
