Well guess what
These little people grow fast
My son outgrew his
Car seat. I Didn't feel comfortable with just the lap belts for a kid his size, in my state he's required to use a booster seat
So I found a 3 point harness
It will keep him away from the metal dash in case of a hard stop.
...pic... You guys who put in a shoulder belt won't have this issue
This is just an option for those of us who just have lap belts
