screaming in car seat

Megan
My little Sawyer Olivia is 11 weeks today and she still hates her car seat :-/ I make sure she is fed, burped and has a dry diaper before we leave, but she screams 95% of the time she is in it. 
Does anyone else have this issue, or have ideas to help? 
I'm using a britax b-safe 35 and it seems fairly cushy and soft and is one of the highest rated seats.
