I have custody of my 2 year old daughter. Her mother has been to rehab and jail. Now she will ask to have her over night. I allowed it because she's on probation and I want her to have a realationship with her daughter. However, when my 2 year old comes home she wines for me for 3 days. This last time, she did the same thing and potty training went out the window. What is going on at her mother's house that she comes back and acts like that?
