So my LO HATES the car and cries basically the whole time, Especially if he has a dirty diaper or is hungry, He screams. My LO likes to be moving, so I reach into the back and kinda jiggle his car seat... and majority of time it calms him down. Are there any other Mom's that do this? Or would a better option be to just let him cry until we get where we are going? On another note, Should I be worried about SBS with this, because I know I am not doing it violently but his head must be moving a bit. Thoughts?
