Apparently, I'm not the only one who thinks Friday = family fun. There is now an initiative, complete with dedicated website, to turn Friday nights into family night. Check out the website here for more information and for some ideas about what to do with all those Friday fun nights. For even more ideas, check out this article on msn today.
One of my favorites from the list is the old standby treasure hunt. With my oldest, we would dress like pirates (bandana and mock earring anyone?) and comb the backyard with my homemade treasure map in hand (tea bags work great to age plain typing paper, and don't forget to burn a hole or two - the best part of making your own map).
If you're looking for something a little more spur-of-the-moment, try digging out those leftover plastic Easter eggs. We've been known to have many an Easter egg hunt in July. Just fill them with pennies, bubblegum, small toys, or even pretty rocks. Any small "treasure" will do. For an even better twist, convince your husband to fork over crisp $10 bills, stuff the eggs, and have the kids hide them for you. Then take your loot and go get that well deserved pedicure!
