It sounded like I wrote this post. My daughter 15 months is doing the same exact thing so i bought her a potty. even if she's playing if she goes and points or shows interest in the potty i take her diaper off and sit her on it with a book or stuffed animal.. she's only gone on it once but its a start. she had gone in the bathroom pointed to the potty and rubbed her belly so i took her diaper off and there she went. I dont push it I follow her lead and seems to be working out pretty well. Good luck.
