I have started too, The most success I have had is with puzzles, she can do a 9 peice puzzle all by herself now. Also flashcards work GREAT. Target has some that are letters, numbers, colors, and words I think I paid only $2 each or so. What all have you started doing with Cohen? I need to start looking into preschools, we arent starting her this fall, but im sure next fall after she turns 3.
If you don't have anything nice to say, don't say it at all.
