If you want to know if your child is ready for potty you will note it in her behaviors. Like does she gave you any expressions when she wants to pee? She should be able to note if she wants to help herself. Like making faces. Especially if she is going for a long call. That way you will know when she wants to help herself. If you start getting this small clues then it will be easy for you. Like if she starts making faces. That means she wants to assist herself. You then take her to the potty. If you keep on doing this she will understand. With time she will be taking herself there. It is a long process but she will get used. This is the way you can train her in other things to. It will be cheaper if she is an upright kid. Meaning she easily understands things fast. I hope this will be of help to. You can alert us of the progress.
