I watched some movie on tv back around 2003, but I only remember the ending.
The mother is struggling to put a boot on her youngest daughter, for whatever reason. The mom is getting angrier and angrier about the boot, scaring her young daughter- who is crying hysterically to get her mother to stop. The girl’s two older sisters- who were waiting outside to play with her- come inside in time to see their mother murder their sister in frustration. I remember they were both shocked and upset, and then the scene jumped to the mother being pulled out of a courtroom, being guilty of murder.
The only other thing I remember is the credits that play, which feature the other girls playing Ring around the Rosie as sad, mournful music plays.
