Swaddling a newborn.
Finding the beloved blankie for a toddler in footie pajamas.
Tucking in a child after the fifteenth reading (that night!) of Goodnight Moon.
Pulling a jacket over the sleepy, sullen high-schooler you're driving to school after she missed the bus.
Covering the teenager who came home late from the party and crashed on the couch.
And, when there is no one else around, tucking in this character.
