Put him in a button up shirt. And leave his shirt unbuttoned and strap him in than do his buttons.

Thank you, I'll have to try that!

So my two year old is forward facing in a convertible seat. His seat is a Recaro five point harness. He is pulling the chest buckle and I can't get him to stop. I was reading that the car seat is pretty much useless, without this buckle correctly positioned at arm pit level.What can I do to stop him from pushing it down to his waist? Any suggestions are appreciated!
