DD (2y+almost 5months) this last week is doing something different when she talks. Whatever the strongest word of a sentence is (usually the verb) she repeats it multiple times. So "Ah shaw dough" ('I shut the door' ) has become "Ah shshshshaw shaw shaw shaw shaw shaw shaw shaw shaw shaw shaw dough...."
Am trying to be patient, let her finish her own sentence and then say it back properly to her, but found myself cutting the chase today and saying the last word. I think she's just playing with language, but could it be something bad in her language development? Anybody else's child do this and then outgrow it?
