It will be very limited if there is even any. Something about a liability issue. But there are still things you can do.
Mine are fairly young (7 and 9) and I personally would like to find things they can relate to.
In the past...
We have stuffed bears and donated them to the local children's hospital (My oldest was 3 then)
I made hair bows and my oldest was 4 and she helped attached them to beanies and headbands to donate to Queen for a day. A nonprofit that serve to brighten cancer stricken kids day.
In lieu of a gift exchange we had girlfriends over for a shoebox frolic for the homeless. We filled them with toiletries, gloves, socks, a toy (for a kid's box), puzzles like sodoku (for a grown up's box).The boxes were donated to the local shelter ***Hint hit your dentist for toothpaste and toothbrushes. They can really be generous. We also did this with my daughter's 3rd grade class. Boxes can also be donated to your local school district.
Have the kids do Random Act of Kindness. My daughters had a great time with this. Their teacher even let me pull them out of school for half a day. This really pimps out the idea of giving because it does not factor in whether it is deserved or not.
Ideas:
-snacks and beverage for the salvation army bell ringer
-cashing in your coins at coinstar and giving it out the cashier for the next person inline at the register
-drop bagels at the local fire/police station
-hand out had warmers to crossing guards **ooops you're in TX maybe not =)
-dropping a box of chocolates for fast-food workers at the drive thru
-take coins to parking meters & vending machines
- search internet for more ideas.
Go to a Special Olympics event. I'm not sure if kids are allowed volunteer time but cheering from the sidelines can brighten those kids' day. I personally know because I have one of those kids =).
Do a money jar. Every time you think of spending, like ordering pizza or dining out but consciously opted to eat in instead...When you skip a movie and decide to watch a DVD instead... Put the money you would have spent in the jar. At the end of the month you will probably have enough money to buy a chicken, a goat or even a cow for a third world family http://www.heifer.org/gift-catalog/entire-catalog.html?ms...
You can also make those simple knot fleece blankets. Small sized ones can be donated and delivered to animal shelters.
