Anyone’s baby does this?

My sweet 7 month old baby just started rolling his eyes back & sort of flutters his eyes, as if batting his eyelashes at me, this lasts only about 2 seconds. Does it maybe once a day No other body movements or weird things. I’ve noticed it when he’s tired & ready for a nap. I’m also thinking he does it playing as if it’s something new he’s learned & does it because he knows how. I’m still freaking out & mu anxiety is through the roof because I googled 🤦🏻‍♀️ We go see his pediatrician this Friday & will be mentioning this
