At 19 months, I would not call DD's toddler talk gifted at all, although she does seems ahead of her 'friends'. Her speaking is not what makes me suspect her to have above average intelligence.
amazed that she can now use most pronouns correctly, plurals, and can indicate possession. Her vocabulary is...I don't know. I alot. Do people really count? Oh, but her pronounciation is awful. She can't really say "L"s, her dipthongs are a little off and she constantly leaves off the last consonant. She has a tendancy to just repeat the first sylabble twice for two syllable words ending in -er. For example, "diap-diap" for diaper, "stroll-stroll" for stroller. I have no idea why. Of course, then she can say names of dinosaurs almost perfect.
DD has always had a remarkable receptive vocabulary. I remember at 8 months she could put her hands in the air when asked, click her tounge, point to her hair, nose, mouth. Well before a year she could point to many body parts, point to almost anything in a book, had maybe 10 signs, and she would follow 3 step directions. But, she was not an early talker. Before her first birthday she could only say uh-oh, tickle, mama, dada, moo, and roar. But, an example of her asynchrony is that many of her very first words were colors and letters. In fact, we didn't know she really knew (we suspected) her colors until she started talking. Within weeks of her starting to talk she said "Mama, I need help."
I think it is funny she refuses to acknowledge the word 'and', and instead smooshes the two words together. "Please follow me, Mamadadda".
And, by far the oddest thing DD does is use a completely made up word-- "Ah-boe" for the words, this one, here, there, that, etc. She began using it at about 12 months. "which book do you want to read?", "Ah-boe", pointing to book. Now it is "Daddy sleeps ab-boe, Mama sleeps ah-boe" or "I want ah-boe cup". She still does this!
