I have a close friend who started both hers at 15 months. She started slow by just having them sit on potty before morning diaper and bedtime diaper. Then for a few weeks put them in pull ups and set a timer and everytime it went off would sit them on potty. She did it slowly and with no pressure. Both were fully potty trained by 21 months. I plan to try her approach with my 14 month old next month. I'm expecting baby number 2 late April and would love not to have two in diapers full time.
