The value of language

Peter is developing nicely, but I find myself swinging between the poles of wishing he could speak words (clearly, at least) and hoping he stays just the way he is. Just this evening I, for lack of a better way of saying it, nagged him that he needs to use words in order to better define his pointing and whining. Then later this evening he strutted around squealing, and I found myself loving the pure juvenile joy of the noise. He will start speaking fully formed English sentences to me, and I will greatly appreciate the coherence of the message. But will it be the same?
