M.,
My son is almost 11 months and from the very beginning he has always hated the car seat. I just purchased his convertible seat and cannot wait to turn him around, hoping that does the trick. I would definetly not swat her as some have suggested. At 11 months old, she is too young to understand what that means. When my son acts up in his car seat. I just try to talk him down, I know he doesn't really understand but I talk to him like he does. I try not to show him frustration or anxiety. Do either of you sit in the backseat with her? Whenever I go somewhere with my husband, i sit in the backseat with my son and we just play with all his toys. When I am by myself, I sing to him or keep some toys in the front seat, and hand them to him as he runs out! Hopefully, she will grow out of this soon. Good luck!
