Last year my youngest would cry on the bus. She would miss her mom and dad, but she especially missed her big sister who went off to middle school and couldn't ride with her and walk her to class anymore.
So I found these vertical badge holders at the Dollar Tree (my FAVE store). Though the also sell them at Wal-Mart and Office Depot.
I took a couple pieces of scrapbooking paper and glued a photo of each family member along with their name on them. Creating mini scrapbooking pages.
The pack of 10 badge holders can hold 20 different photos - so you can add grandparents, extended family, pets, even favorite toys.
Once the mini scrapbooking pages were done and put into the badge holders I secured them together with a binder clip that I found at Wal-Mart.
Plus being covered in the hard plastic badge holders protects the photos so the album will last even when played with by little fingers everyday.
