shaken baby syndrome I didnt know you wasn't supposed to shake a baby. I mean not like the kind where you hold them up and shake them. I mean just like hold them in your arms and shaking. I'm afraid I have been doing it to fast. Because I just sit and shake him in my arms like a rocking shake. I want to ask his doctor if that has caused him any harm. I read that if you mention it to them that they report it and will take baby away. I'm really concerned ....
