Sometimes I wish it was legal to leave your children in the car for 2 minutes

My life currently is all about running errands- groceries / pick up a lot of construction materials for our home project / dry cleaning / other admin tasks. I find it absolutely exhauuusting to do all this with a baby; especially with the very cold winter and the snow. I would never do it but sometimes I wish my child could stay in the warmth of the car for 2 minutes.
