I never missed an election when I was a child, my parents took me to vote with them and it was not a problem. Even the littlest ones can wait for you to vote.
Most places will have things for the kids to do, ballots the kids can use to vote on as well (not real ones).
You do your children a service to bring them to the polls, it will help them to learn the meaning of their republic, and the fact that it takes _citizens_ voting and running the polls to keep it.
I’m not sure you understood. My kids do come with me to the polls. They know who I am voting for and why. However, I would rather vote early and wait 20 minutes, than vote on election day and wait for hours.
