Things that have worked for other parents: getting rid of the baby bucket & getting a rear - facing convertible seat; putting the seat slightly more upright (for
older babies whose heads don't slump forward & no more than 30 degrees), putting the
radio station to static & having it the same volume as the crying, singing, trying different kinds of music, sitting in the back with the baby (
obviously only works if someone else can drive:)-RRB-, having toys that are just for the car, only going somewhere when baby is sleepy... I'm sure there's others, those are the most common
