Hi Hobbgoblin - can I join you in the hope that my ds is also G&T?
Ds started speaking early too. Around 6-8m was definately saying daddy and nanny (little tike forgot mummy for a while) and was also doing animal noises. Roar for lion, moo for cow and baa for sheep, when prompted.
By 9 - 10 months could say words well like mummy, daddy, nanny, grandad, ball, book, bike, car, drink, balloon and others.
By 1year was stringing words together - mummy car (for mummy's car),daddy drink (for daddy's drink).
He's now 18m and can count to 10, knows colours (including distinguishing between pink and purple), can tell you his name and where he lives, how old he is. Knows a vast array of animals and their noises, knows lots of foods. Can tell you most of his body parts (arms, legs, hands, nose, eyes, hair, willy) and can tell you what clothes he wants to wear. He will also be able to coherantly tell you what he did at nursery ( did painting).
There's plenty more but don't want to be too gushing!
Can't tell you if he is gifted or not (obviously I think so) but is definately advanced on the talking scale.
It sounds like your DD is a bright spark and will love to chatter endlessly to you soon. Just start being careful what you say around her now as they pick it up oh so quickly!
