I'm sorry this has you upset and I would be worried too ((madisgram)). Are you on good terms with her husband to talk to him?? Did she tell you she did this - how do you know they were left unattended? If you can't let her husband know and hope he'll do something, then yes I think you should call child services. It's dangerous for kids 3 and 5 to be left unattended - it's not right to turn away and pretend it's not happening. I understand it's very hard to do to a friend.

Just make sure this isn't a one time incident and you're sure of the facts. If there's an easier way to ensure the kids safety then try those first. You also have to take care of yourself and know when to step back. It's a hard judgment call but I hope someone cares about these kids.
