I wouldn’t want to turn normal interactions with my kids into rigid interactions forced into agile format.
The purpose of standups is to go fast and not waste people’s time with friendly, casual conversation. Using that format to engage with your kids is the opposite of how you should be encouraging interactions. You want to get involved and encourage natural discussion.
Jira is useful for tracking things that you’re not involved in and giving reports to higher ups who want to drop in and see progress reports. Again, not the dynamic you want to use with kids.
Just interact with them like normal human beings. Show interest, ask questions, have conversation. Don’t take the things people loathe about forced workplace interactions and make that the dynamic of your family.
