What happened the last time you tried to catch her when she fell? She never learned how to stand on her own because she had you there to support her. Most of us only learn to grow when we are forced to. She has no reason to grow with you around. You've been indulging her for a very long time and she looks to you to take care of every thing. It takes much longer than a week for us to really put new and better habits into practice. She has to want to do it to better herself for her HERSELF, not just so she can keep you by her side.
It will take a long time for this to sink into her brain. She will make a lot of mistakes. But she is her own person and it's time she started acting like it.
