Every time I had a grandchild I would go to the hospital to see them and take pics. Go home and make an instant 6x6 accordion book and return the next day and give it to my kids so they would have the first moments of birth to share pics with others and also a keepsake for them to have.
I have taught youth classes where we decorate the cover of a composition book and they get to personalize it with their name and likes.
I have an old neighbor girl who has come twice to my house since being married and we create a bunch of cards together so she has a stash.
