A.,
You are a very bright young lady. It sounds like you are a very young mother, who is responsible and respectful. I am glad you have the support of your mom and are willing to listen to her.
Potty training usually starts close to the second birthday.Some kids, esp. girls can start earlier. My daughter was trained by 18 mos. It only took a week. My son was 2. Two other sons were 3 and one was 4 before being completely trained although he had trouble with constipation.Kids usually give you signs that they are ready to learn.
Keep up the good work, A.!
