Just had a disagreement with DH
On the way to dropping off 2yo, DH pops into the shop for about 2/3 mins leaving 2yo in the car.
It's parked on a busy road, lots of pedestrians can't see him from the shop, car is locked. 2yo can also unbuckle own seat belt and open the door.
AIBU to say that you can't leave 2yo in this situation and either take 2yo in or don't go to the shop?
