Are you kidding me Balto-Slavic languages??? 1. Latvian and Estonian belongs to Baltic language family. 2. Estonian language has also nothing to do with slavic language also as it's a branch in Finno-Ugric languages.

Also using wikipedia as a source of information is questionable. As the pages related to post-soviet era countries are propoganda war zone for Russia and the countries itself to promote the point of view needed.
