Yes, he reads in English. Actually he loves the language so much that does not need any special teaching at all.
He prefers to read in English, then goes Russian and then Georgian (despite the fact that he is studying in Georgian-school)However, he had several young teachers - just regular English language students; we had two lessons per week during three or four years. Now he goes on independently.
and probably there was some small contribution of his mother too
We frequently communicate in English. For him it's very natural to come and to start talking to me either in English, or Russian, or Georgian - all languages are of the equal value.
