My son did that trace thing at 2. I do believe it's normal. They are distracted by something, and while we think they are in a trance, they are actually engaged with something other than us. I just figured it was a 2 thing. But he's now 4 and will still space out while talking. I think he loses his train of thought or can't find the word. He is perfectly normal, i might add.
Also, the hugging and kissing thing. Some kids do this at 2. I'd have to see it, but I'd say it's normal. It's socially awkward, but normal.
lastly, lots of kids are picky eaters and fearful. I have a friend who couldn't take her son places till he was close to 4. he couldn't stand noise. There is nothing wrong with her son. He is now a happy kindergartner. He just didn't like certain things.
Get a second opinion, but if the doctor says she's normal, chances are, she is normal. kids are weird. I use to worry there was something wrong with my oldest, then I realized, kids are weird. They are socially strange, with weird ticks. They do things like insist things happen in certain ways, that only so and so do Y, etc. But it's all just a part of them learning how the world operates. They also have stuttering phases, shove everything in their mouth (my oldest would lick me!!!!!!!!!!!!!!!!).
I hope you find answers, but I'd say everything you mention here falls under "normal."
