Do you or your spouse have special things that you do with your kids when the other spouse is away for work? My husband is often on-call, and when he gets called in my daughter and I often have "girls nights" and paint our nails.
When I was a kid, when my dad was away on a Friday or Saturday night, my mom would take us to the store to get tv dinners and we'd pick a movie to rent.
My husband's on-call schedule is pretty packed in Q4, so I'm looking for small, special things to do with my daughter so she's not focusing on missing Daddy.
