I guess, no one puts baby as young as one in school. I mean not the one that I know of. I put my baby in nursery (pre-school) when she turned three. And to the kid as young as 1 there is no need to teach him. Let him observe, pick up words that you people say at home, sing rhymes to him, songs to him, cuddle him and give him little toys that are appropriate for his age to develop his intelligent quotient. At one, let him just feel, see, hear, adjust, react to life around him. :)
