No it is not to early! Each child is different. Just go at her pace. If she has an accident then oh well. It happens. My daughter showed interest at 14 months. Yes 14 months. lol She is a pro now. I never forced her, but when I went she would sit on hers. So we took it from there. She may show interest now and then stop. Thats ok too. Just take it one day at a time and go for it! Good luck!
