Normally, they have work times of about four hours per day for the volunteers. But i didn't care about that. I had my breakfast at 7.45 am and spent some time at home with my coordinator, before I went to work.
The bus drive to work was just about 15 minutes. I started working at 10 am. From 10 to 12 the children had something like school. We painted, buil towers of bricks, made puzzles and so on. They had a little break and we moved on with school.
At 1.30pm was lunch. I ate together with the disabled. Then I had a break of about 30 minutes, sometimes shorter, when one of the disabled came to me earlier. In the afternoon, they had another two hours of school and we danced a lot. I went home between 4pm and 5.30pm.
It's also no problem to made a day of, when you plan an excursion. I did it once and worked a day on the weekend too. They're really lucky, if someone likes to help on the weekend.
