S.B.
I agree that little kids can just simply do weird things.
It's good that you will be following up with the pediatrician. But, I'd like to share something deadly honest with you.
I grew up in the San Francisco Bay Area and I vividly remember walking around as a child with my eyes half shut because I thought people would think I was Chinese.
The blonde hair would never be a clue to the contrary, right?
I was just noticing differences in the people in the world around me and "experimenting".
Fortunately, I got over that phase and my mom didn't drag me to a neurologist or psychiatrist. I was just being a weird and imaginative little kid.
I also alternated closing each of my eyes. I noticed that if I closed my left eye, I could see one thing, If I closed my right eye, I could see something different. When I opened both eyes, I could see everything in the middle at once.
For what it's worth, I was found to have a very high IQ in spite of my little weirdities.
I wouldn't worry. Follow up with the pediatrician and perhaps get an eye exam just to be on the safe side.
Your little one might do lots of funky things before it's all said and done and be perfectly normal.
:)
Best wishes.
