I have a 9 month-old boy and you may as well have been describing my son. He will often shake his head back and forth when he is sleepy. I always took this to be his way of self-calming before he falls asleep. He is constantly waiving his arms and squirms like crazy. I work for an Early Intervention program and feel as though I am pretty good at recognizing "red flags." I think what we have are just active little boys that are going to wear us out when they start walking. I just enrolled my son in a Little Swimmers class at the Gaulter Center and hope that this will be a good outlet for him. Best of luck.
