Volunteer Work in Buenos Aires

Hi

Its been almost 2 years since i travelled to Argentina and im really wanting to return, im thinking about going back next year, but this time im thinking i would like to do a bit more then just shopping and walking around sightseeing.

I was thinking about this time doing some sort of volunteer work, just to get a different experience and see things from a different perspective you know what i mean?

Id like to do some work with children or young adults and i was wondering if anyone had any sort of experience with volunteer work or knows anyone who has?

Any sort of information would be good, ive never done anything like this before and i dont really know where to start

I am Argentine and do different types of social assistance, may contact you to different places.
