Unbelieveable! What the heck was she thinking? I can't believe she didn't flip out at the party when she saw her "babysitters" there. Whether the door was locked or not is not even the issue...common sense tells you that. An unsupervised child at home alone is unsafe...PERIOD. There are just too many dangers inside the home for a child that age. I hope child protective services steps in because something just ain't right...
I don't even let my seven year old son go to a public bathroom by himself. I used to take him into the ladies room with me when he was younger. Now that he's older he outright refuses to use the women's bathroom. And, rightly so. Sooooooo, now I go into the men's room with him (after annoucing that a lady is coming in) just to make sure nothing happens to my child. There's nothing in there I haven't seen already anyway

and I've never encountered anyone who had a problem with it. I'm sure all of you parents (and even non-parents) can recall cases of children being molested or even murdered in a public bathrooms...sign of the times we live in. Sad.
I don't understand how she could have had a good time at that party knowing her baby was home alone. That just baffles me. Sometimes, it takes all my concentration to have a good time when I go out with my hubby and our son is with his grandparents. Maybe I'm just a worrier...
