And was it easy/successful right away, or a challenge? Do you wish you would have done it sooner or waited longer?

With LO1 we potty trained at 2 years and 4 months old and it was pretty easy with the 3 day method, but she was ready. There were some challenges but we made it through and she day/night trained at the same time. LO2 isn't quite 2 yet and I know she could probably understand the concept since she tells us she pooped, or has to, and asks to be changed but I think she is still a bit young. My mom thinks she can do it but I don't want to push too soon, so I think I'll wait until the spring.
