Extra photos, small scrapbook or notebook, photo safe tape.
This is a perfect activity for extra photos. Give your child your extra photos and a mini scrapbook. Let her cut out the photos and stick them to the scrapbook. If your child is old enough to write, let him or her journal on the pages. If not, just write their thoughts for them. They can keep adding to the book until it is finished and keep their own book for years to come!
