Thanks for asking!
This is only the second year that I’ve done this, so I am still learning, but here’s a list of what we put in last year’s.
Reusable water bottles
Candy (Because, everyone should have candy!)
McDonald’s Arch Cards
Dental Hygiene Kit
A letter to let them know that we saw them
Something we didn’t include, but learned was much needed: City Transportation passes (bus, lite rail, subway).
This list will be updated continuously, so stay tuned!
