Awesome!

Check!!!!

What do I get for a 4 year old???

I would put video games in there (either Nintendo, Playstation or Wii), maybe a customized sweatshirt or hoodie with their last name embroided on the back, your date on the wrist?
Whatever sport they play, you can buy them either a baseball glove, football, hockey stick or even their favorite team jersey. Depends on how much you want to spend.
