Our grand child is 4 months old and appears to be developing normally; however, whenever she is in her car seat and the auto begins to move, she begins to cry. Most children we are in contact with react exactly opposite...the movement of the car soothes them and often causes them to go to sleep. If the trip is 15 minutes in length, she cries for 15 minutes. If the trip is 60 minutes, she will cry for an hour. What is causing this? Is it an inner ear issue, visual perception issue causing car sickness? We need some help... Traveling is now very stressful for the entire family!View Thread
