Hello! I'm no expert, but DD3 shows some of the same interests, and she's our "normal" child. DS5 showed the same interests as well, but way earlier than DD3. I think showing these interests is definitely a preschool thing, but extreme or "higher" levels of interest and intensity, especially at an early age, towards those things can be a sign of GT.
DD3 loves music and to sing, but she wouldn't stare at a music book at all. But DS5 did something very similar with animals and animal books before age 2. DD3 is my helper; whereas DS5 was not at all interested in helping until DD3 came around. ha!
Sounds like she's keepin' you on your toes though, which is always a good sign.
