Carseat Woes...

Anyone else have or had an infant that HATES the carseat?  With the exception if one time in the past week Brody is hysterical when in his carseat.  I think the reason why he did not freak out the one time was that he was already asleep when I put him in.  Today I desperately needed to get out and run a few errands and the sound coming from the backseat was horrific!  It sucks because there is nothing you can do to help him.  I am hoping this is a phase... Cabin fever is no fun and neither is a screaming baby.  Anyone have any tips or advice??
