Don’t have a bubble machine? Just have some of the older kids blow bubbles for the younger kids to catch! After the first ride, have the other children line up for their turn at a wagon ride, or bring in a few wagons and ask other parents to help give rides to the kids. Little ones may also enjoy some wrapping paper to crumple into balls. If you like, you can even supply some stickers and crayons that kids can use to decorate the boxes. Some ideas for notes may be a memory of the first time guests met your baby girl or their hopes for her future. Set a date for the opening of the time capsule, such as on her 10th birthday, and ask friends and relatives to contribute an item she may like or need on that occasion.
