Hi kind people. My name is Evgeny. In the photo my family the wife Yulia and the son Alexander to him 3 years. I try to help people when I have an opportunity, but now my son needs medical care and there is no money. We have moved to Russia to Siberia from Asia. I have a work small work. My wife Yulia stays at home with him now because with his disease don't take in kindergarten. My son Alexander has a problem with teeth. We 2 times a day have cleaned to him teeth and have given tablets with calcium, but they spoil. 3 teeth very quickly spoil, and it is necessary to remove nerves. His teeth begin to damage anesthesia for treatment of his teeth, in hospital we were told to wait for 6 months. It is possible to address to clinic for money. My son can't transfer from pain him still small. We have forgotten as he smiles. We with the wife worry about him strongly. On treatment necessary 450 dollars. I and my wife Yulia, we will be very grateful to kind people who will help us.
