I was visiting a friend and her new baby in the hospital Monday night. I had my 4 year old son and my 7 week old son. When we got ready to leave, I strapped the baby back into his stroller, and he immediately started screaming and crying. I rush the 4 year old out the door so we can get down to the car and feed the baby. It was only after the trek to the car that the 4 year old tells me he had put his 2 toy tractors in the baby's seat. I had strapped him in on top of them. : ( He was screaming because he was being jabbed in the back by toy tractors--and I just rushed to the car thinking he wanted to eat and didn't even check. His back was red, and I felt horrible. : (
