Maybe your kids are too young for a sleepover extravaganza, or perhaps you just aren't mentally ready for that kind of drama. So instead, invite guests over during the day to celebrate your child in their favorite pajamas! Play games like Musical Pillows, and instead of Freeze Dance, play Sleep Dance where players fall to the floor and pretend to be asleep when the music stops. For dessert, serve colorful cereal marshmallow bars (with candles, of course). At the end of the party have everyone sign and decorate a plain white pillowcase with fabric markers for the birthday girl or boy.
