Shreya's first alphabet - Not "A"

The first alphabet Shreya mouthed was "X"
Can you imagine?

Now, what can I infer from this?

A) She is referring to her chromosones - which are two Xs

B) Is she saying she has X-ray vision - by picking up objects that are invisible to naked eyes?

C) is she going to develop something like "X-rays"

Ah! I am a typical mother reading too much into this

I think her lips probably prefer to say"X" first
