It’s a tough question to answer in my opinion, because every kid is different and will show signs of readiness at different times. With my oldest, she was about 2 1/2 years old when I stared. She was a tough cookie to train but I didn’t want to be changing her diapers anymore.

At the same time I had an 18 month old who saw her big sister go potty In The big toilet and wanted to do it as well. So I basically trained them both at the same time.

My method was just no more diapers and big girl undies from then on. Lots of messes to clean and patience. I tried a few different methods of rewards like sticker charts and small treats but what my kids really enjoyed were popsicles. Just the otter pops and I would cut them in half.

Good luck! 👍🏼
