My sister writes her kids a letter every year on their birthdays and plans on giving the letters to her kids when they turn 18. Maybe you try doing this on Father's Day this year. Tell them about them, your lives, what is going on in this world and what you are learning from it. This year could be the best year to do it. And it might just be good for you too. Then one day you can tell your kids about 2020 and how it changed you.
