Nicknames? Ok unless the person doesn't like them. Personally I don't care for them.

You would need to check with your state's Child protective services. Do it from a pay phone and you can't be traced; however, keep in mind that if the children turn out not to be responsible and something happens it won't matter whether or not it is legal or not. No amount of laws can prevent an accident after it happens. Only you know if your children are dependable enough to be left on their own for a couple of hours or not.

Nicknames - bob, george, ringo and john. elvis. I think that nicknames are a non issue, given your other question.

Alone for a few hours so that Mom and Dad can go on a date, no, that is okay. Alone for a few days so Mom and Dad can go on a vacation, not okay!
