I have a now 11 week old son and pretty much since birth he is constantly moving. Never sits still. Whether it’s rocking his head back and forth or waving his hand around or kicking his feet. The only time he is still is when he’s sleeping but when he’s awake he just doesn’t stop. He was laying on the floor today on his back and he just kept moving his head from side to side. It’s like thee most random movements. Does anybody else’s baby constantly move?
