Scary! On my way to work today a car was headed in the other direction and the mom was in the passenger see holding her infant (maybe 2 months old based on the size) in the air in front of her while they interacted with each other. Meanwhile the car is traveling over 60 MPH. I know this because they had just passed a car and swerved back into their lane from the one that I was traveling in. The speed limit is 55mph. Car seats and laws about them are there for a reason. Unfortunately laws and seats can't protect children from the stupidity of their parents.
Enough ranting, I feel better now.
Now a plug - be sure parents read the directions for use on car seats because most are installed incorrectly by parents.
