My Sweet Baby Boy

How can it be that my sweet baby boy screams in the car. It doesn't matter the time of day if he has just eaten or where we're headed he cries. i didn't experience this with Micah, he was a happy car rider and even slept. My good friend told me her little boy did the same thing, it didn't get better until he was 4 months. That means i have another month at least of crying in the car. It's the most helpless feeling. There is nothing you can do. Even the binky doesn't help. Big brother tries to help by saying 'Josiah don't cry, we're almost there. Don't cry Josiah.'
If anyone has any ideas on how to fix this problem I'm open to some suggestions.
