While I think having new bed-warmers spend the night before the ink is dry is generally craptacular parenting, I can't help but say...
Hey, Tennessee! Welcome to the 21st Century!
lol Proserpina. I completely agree with you, but we have so many cases where the parents were never married and it has always seemed really silly to tell 2 unmarried people who lived together when a child was conceived and born that they can never have anyone spend the night.
And, in many judicial districts, up until the past 6 months or so, if 1 party wanted a no paramour clause it was almost always unilaterally put in place by the Judge (and these were post divorce and/or non married situations). If both parties agree to a no overnight guests clause, it's one thing, but that wasn't what was happening.
I have a feeling that even though we have now entered the 21st century that the standard of harm to a child of an overnight guest will be very very low to prove for awhile. But it's a step in the right direction.
