I’m leaving for a 6 day work trip next week leaving my too-good-to-be-true husband solo with a preschooler, toddler and an infant.

I’d like to do something to let him know I appreciate everything he does. I was thinking of secretly getting a babysitter and making his brother take him out for dinner one night. Anyone have a better idea? What would YOU like from your spouse if the tables were turned?
