Ok so I have no real business giving advice on shopping but hell, I do it and I have small kids so I am on the prowl for good stuff. I found a bunch of cool stocking stuffers for my three year old boy and here goes:
Batman crayons from Lil Doodlers on Etsy.
Matching game by Lemon Tree Studio on Etsy.
Buzz Lightyear notebook from Red Elm Designs on Etsy.
Shark chalkboard placemat from CustomKids on Etsy.
Exploding frog soap from Howards Home on Etsy.
There are some ideas for now. If you have girls, these come in girl versions too and some are pretty gender neutral. Chime in if you have other stocking ideas!
