How Old Is Too Old To Sleep With Your Kids?

My wife finally admitted it last night.  She's still sleeping with our 5 year old son...not because he's scared of the dark...but because SHE's sad about closing this chapater of his childhood.  She cherishes cuddling with him and falling asleep at night with him.  She knows it won't last forever, and is having a hard time breaking HERSELF of the habit.  Meanwhle, he's fine.

All kidding aside, I understand the sentiment.  I, too, struggle with the bittersweet moments when I look at our kids and realize they are growing up.
