What are the stars doing?

Me: Look up there, you can see so many stars tiny in size and shining!
A: Ah! Stars, amma , stars!
Me: Can you count how many stars are out there?
A: Trying to count those that fall in her sight
Me: There are many stars
A: Yes, there are many stars
Me: What are the stars doing there?
A: They are doing 'twinkle twinkle'
Me: 'Twinkle twinkle'?
A: They are doing 'twinkle twinkle'
and she sings the twinkle twinkle rhyme for me
