I know the importance of supporting a newborn's head, because it is so large relative to their body and they don't have the strength to hold it up. And I have heard that they can get spinal and brain damage if their head flings back. I am a little worried because there have been a few times when people were holding or passing my baby when his head fell backward a little. Is this something to be concerned about? Baby never cried or reacted at all and it has only happened a few times.
