I think people made fun of the shape of his head at the beginning of his life, so Paris probably covers it so they don't keep making fun. Or to protect him from the sun when outside.
His head shape is odd. People were concerned he may actually have something wrong with him and that upset her so she put him in hats. He does seem to be a bit delayed in some of his physical milestones. He is walking very unsteadily (based on the video) and he’s over 18 months now. My guess is he has low muscle tone.
+1 Anyone who has worked with kids who have special needs would likely think the same
My son has low muscle tone so the delayed/unsteady walking was a giveaway. The head shape - he may have a flat spot on the back. I really don’t know. But it’s not normal. But its her business.
