A group of wonderful Muscovites visited this orphanage on March 19 (not for the first time) and delivered toys, clothes, medicines, juices, etc.
Lots of info (in Russian) on how to help Russian orphanages is here, at the site called Dobrodel.ru.
An excerpt from the Q & A section of Dobrodel.ru:
I don't have much money - can I donate only 50 rubles [less than $2]?
For 50 rubles, it's possible to buy 10 pairs of socks, or 14 soap bars, or 5 bottles of kids' shampoo... Is this not a lot?
