Saddling a Horse, Buckling a Child

When I was little we had horses. One of the horses liked to inflate his belly when he was saddled. After he was saddled, he would exhale and the saddle would be loose. Buckling in my 3 year old with a five point harness car seat is kind of the same experience. Ryan arches his back when he is being buckled in and I have to tell him to put his back against the seat to make sure he is buckled in correctly and everything is the right tension. I don't think he knows about our old horse but he sure acts like him when it comes time to be buckled into the car.
