Well, talking is what dd is best at, so please don't use her to compare! She started talking at about 10 months, and her first words were "duck" and "Quack," except she said "cack." After that, her speech took off like a rocket and she had over 100 words by fourteen months. They were all words that she used correctly to name objects, and they sounded enough like the real words ("bappuh" for diaper, for example) that we knew what she was saying. Short sentences started at about 18 months. This was exciting, but sometimes frustrating for her, because she thought that she had figured out the way to get whatever she wanted! It really shocked her that, now that she could make herself understood, Mommy and Daddy still weren't going to do what she asked all the time! :LOL
The really good thing about having an early talker was that she never threw those two-year-old tantrums that are often triggered by a child's frustration at not being able to express herself in words, and she also never used her hands to communicate with other children (pushing, hitting or grabbing). The not-so-good thing is that those tantrums came a year and a half later, and they were VERBAL tantrums that sounded something like this: "Well, if I can't have ice cream, then we are going to LEAVE the playground RIGHT NOW, and we are NEVER coming back AGAIN, and we are never going to go to the museum, or the library, or do ANYTHING fun EVER, we will just STAY home all the time and stare at the WALL and do NOTHING NOTHING NOTHING." My little genius.
Anyway, I think parents worry a lot more abvout speech than they need to. At age two, dd and the other kids her age were all in different places with their language, some kids barely talking at all, and by now (almost four) they are all speaking fine, for the most part.
Boy, I sure gave a long answer, didn't I? Must run in the family! :LOL
