I’ve got 4 younger kids and besides the communication part the most important thing I ever did was freezer meals. Every year before season starts, I spend about. 12 hours in the kitchen making a freezer meal for every night I am gone. Evenings are the toughest for her with the kids, so this is a huge deal. I made 32 meals for her this year and pretty much exhausted all my game meat except for ground elk. The first year I did it, she cried her eyes out because she was so touched by the gesture. It’s a little thing for me, but a huge thing for her.
I am sure the meals you froze were great - but nowhere near as great as showing her that you understood the workload she would have with you gone, and you wanted to help with it in advance. That's priceless.
