It's interesting how deep the myth that if a child is 'truely gifted' that they will be advanced in every area. It may be that the muscular control to speak clearly is just 'age appropriate' for your DD, while other areas are clearly well above average.

I know you'll love her no matter where on the levels of giftedness she turns out, so just enjoy her. Be careful when placing her in group care. Spend some time with a truely heterogeneous assortment of toddlers to get some confidence. She isn't following the normal path of development.
