When my 9 mth old ds gets tired he does this really strange thing where he shakes his head from side to side. If he's in the buggy he bangs it off the sides to my (and everyone elses) alarm.
He does it in his cot too. He does it so much that the hair on the side of his head isn't growing as much as the stuff on the top and it's getting a bit mohawkish.
Just wondered if anyone else's baby did this?
