Hooray for DD. How old is DD? I am very confused about this whole process. DS is 20 months and I just am not sure when to start. I am trying to talk about the potty, but I have not actually purchased a potty chair. I can tell he has absolutely no interest and does not care one bit about having a wet and soiled diaper. He did tell me one time last week when he pooped, but I don't think I am going to even put out a potty chair for another few months. Please give updates.
