Well I haven't really started to potty train my youngest yet. I started my oldest when she was around 2 years old. I just asked her if she had go potty and put her on her potty. I would set with her for few minutes and sometimes she would go and others she would not. I think letting her go bathroom with me helped out alot also. When ever she did go "potty" I told her what a good girl she was. Finally she got the idea and told me when she had to go.
