Does anyone else have a toddler who was clified as "presumably gifted" before 2 YO?

My daughter has been clified as "presumably gifted" by her Dr. and also a developemental psychologist. She is 18 months old and has a vocab of approx. 100 nouns, verbs, adjectives, sounds, and also a few 2 word sentences. She can also identify all of her obvious body parts (ie nose, ears, legs, arms, hands, , belly ect.) She also has recently learned to differentiate from her left and right feet, hands, and ears. She can identify the letter B and can identify how many fingers you hold up, up to 3 fingers, and can count to 3. In order to figure out her clification they used the scale that is usually reserved for identifying speech delays or possible onsets of autism. This scale measures "Developemental quotient" as opposed to "IQ". Basically when they look for speech problems/delays they measure how far down on the lower end of the scale the child is, and although it's not often done (my ped. says she's only had it done 1 other time in 15yrs) it can measure the opposite direction. But they only attempt to prematurly clify a child if they appear and then show to be very far over the average. I'm not sure where to go from here. A certain level of advancement has run in my side of the family. But not to the extent she shows. Because of this though, there are some temperments that are more extreme. Like frustration, she gets frustrated with things; like puzzles, more quickly then a child who is "average". It also makes her tantrums a bit more extreme. I don't want to do anything to impeade her abilites so I am looking for general parenting advice from anyone who has had a similar situation. Thanks!
