8 months old hand and feet movement

Hey ladies,

Well I don’t really know how to begin this. My son who is 8 almost 9 months old rotates his hands and feet when excited. I made the mistake last night of googling it. Out of curiosity to see if it was something to worry about. The first thing that appeared was “sign of autism”.

My heart sank.

He’s meeting all other milestones for his age.

Is this normal for babies his age? Has anyone’s babies done this and outgrown it at some point? What I thought was a cute quirk now has my stomach in knots. 😔
