Sleep overs aren't just for little girl. When I turned 30, I invited 10 of my closest girlfriends and sent my husband and 3 children to his parents for the night! I had all the ingredients for a day at the spa, we did facial, pedicures and manicures.  I served wine and we danced around my living room to our favorite 80's music in our pajamas. I had rented "girlie" movies, pranked called our husbands and later played "light as a feather" and "truth or dare". We stayed up to the weeeeee hours of the morning and had a GREAT time acting like little girls.  One suggestion: make sure you send invites out early so mommies can make arrangements for their families.
