Hi thanks for the responses.... I do not think that she is behind regarding age and after our stint with pt I would be reluctant to involve anyone at this point.... but it seems funny to me when she seems advanced in other ways. So it is nice to hear that other people had indistinct articualtion and their kids were also advanced. People refer to "large vocabularies" but I posted a question asking for what that may mean and so far no one has responded. At 16 months little one had over 100 words some sigend some spoken and at 18 months was over 300 spoken and we had lost count. Would that constitute a large vocabulary? I am thinking of the LOG by Ruf.
