Life / Volunteering in Poland [21]

Hi, just looking for a heads up- if anyone has any info?? =)

I'm living nr Gdansk and would like to volunteer for a charity or something because atm I have quite a bit of free time.

I'm trying to learn Polish but can't really speak so thats a consideration.
I worked with children and young people in the UK and would like something similar or social services kind of stuff.
Any websites I can try? I can get my Polish cousin to help... Thanks in advance.
