I actually believe this would have been her exact reasons for not wanting Caylee around anymore. She might have been a good mother when Caylee was a baby and maybe she had more people to help her take care of Caylee, but as the baby became a toddler, she was more than Casey wanted to take care of especially if her desire was to go out and party all the time. It's just hard to imagine how someone could seem to be so loving to their child in early photos and then dispose of them like some garbage. Of course, we've seen that years ago with Susan Smith, when she wanted to pursue a relationship with a man who didn't necessarily want kids around.
