Looking for English speaking family with kids in Kiev

Hello, May be it sounds strange, but I try to find English-speaking kids to communicate with. My English level is average, and I want to improve it, especially speaking skills. It is a lot of English courses in Kiev, but I think that the best option to learn English - it is to learn it as children learn mother language. Also I have some calls and meetings with English natives and it was very helpful, but people are busy and it is hard to communicate long. Also I noticed that it is not so hard to  be with kids, even if the are crying or doing some funny things.
I can give some lessons for kids like math or Russian...
