Mom thinks Nathan has a speach impairment (sp?) By now he's supposed to be saying 25 to 50 words but he only says 4. Dog (Daw), Cat (Tat), What, and Yeah. We've been working with him and working with him but he just doesn't seem interested in repeating words. When he wants something he'll point at it and grunt and when we try to get him to say what it is before we'll give it to him he gets mad and starts screaming. I think what has us worried so much is that my 15 month old nephew, Eli, is repeating most things his parents say. But Nathan...doesn't. He doesn't even try. It might be off to a speach therapist for us.
