Reciprocate how you can. Weekend sleepover to give the other parents a real date night would buy you a million pickups I had to do anyway & play dates that on balance probably helped entertain my kid if it were me in their shoes.

You need to reciprocate. Why can't you have a kid over on the weekend?

Or offer to have a kid come to your house after school but say because of the carseat situation they will need to drop off and pick up.
