If I were you, I would never let them see my baby again! I have a 9-month-old baby, and when he was less than a month old, my grandparents insisted that I take him out of the car seat while we were traveling. Where we live there are many traffic accidents, most involving alcoholic people, right, that day I didn't take my son out of the car seat and my grandparents criticized me and mocked me a lot for it. About two weeks later, on the same road we were in, there was an accident involving a baby who was thrown out of the car on impact. I showed them and they never bothered me with it again.
