We started to teach Zach some tricks as early as 4 months.. eversince I often to play music like baby eintein, mozart, beethoven, lullabyes etc.. All in the name on my son’s learning. When he was 5 months old ive discovred this downloadable software, called Brill Kids Educational Software http://www.brillkids.com/ , I find it cool and fun to teach my son in a modern way.. However I should still avail the full package to have it complete.. so I decided to look for another alternative, Baby Einstein CDs are too expensive and would it be worth paying for? So what i did and what i do is to repeatedly flashed some cards of letters and numbers to Zach.. And I could see its effective.
