I used to make bags for the kids in the neighbourhood at our old house. We lived in BFe, so we only got 10-15 TOT's tops. So it was super easy to spoil the crap outta them, lol.
Now, we live in a nicer closer to town neighbourhood, so I don't know yet.
I always make bags for my daughter's class at school. I put a plasitc cup and straw in them, playdough (she's 7 BTW, lol), some stickers spider rings, pencil, and a ton of candy. Each school bag runs about $5 each.
For the kids in the 'hood though, I will probably give out bags to the kids she always plays with, but have handfuls for extra for the kids we don't know, or the ones that drive to the "good parts of town" for candy.
