DS is almost 4. He has figureed out how to undo the chest clip. I told him if I have to stop really fast he could get thrown from the car & die. Extreme? Yes but what else can I do??? He can't figure out the piece in the crotch area (it's hard for me too).
BTW we were in a parked car with the engine off so I was not using my phone while driving!
Thanks for all the advice ladies! I also joined the carseat group to see what the women there suggest. A lot of them says positive reinforcement- he gets a piece of gum if we arrive at our destination without unbuckling. So far it's working. Another suggestion is that I contact Safety 1st (manufacturer) & see if they will suggest a clip that is harder to unclip. I will be doing that as well!
