Two people I know have done this--when you sign up to bring them a meal, they let you know that if they're resting, there will be a sign on the door and you can leave a meal for them in a cooler. Anyone else seen this/done it?

While arranging for people to stop by postpartum was stressful at times, I still wouldn't feel right doing this (even though it is somewhat appealing). At a minimum, I wanted to say thank you to friends for the meal.
