Is There A Way To Politely Tell Them To Leave The Older Sibling In The Car?

No more kids are being left in the car, they wait on the porch.

Not trying to be argumentative, but they can walk away from the porch easier than they can unbuckle/get out of a carseat, unlock and open the door, and walk away from the car. Just sayin'

I'd rather have the kid in the car - car parked where the mom and/or I can see it from the living room window - and have the pick up be less than a minute so that there's really no time for something to happen.

Sorry I ahould be more clear. Porch with the door open parent and sibling stay on the porch I have child ready to go. Child can't come in and parent can stand on the foyer with door open if wanted.

Almost like bye bye outside.
