Do it, normalize it, as a parent our job is to keep our kids safe, that is priority. Traveling with kids at a young age in my personal experience has been incredibly positive. Showing them the world, other cultures, sharing in the trials and tribulations that no doubt will arise will do wonders for their development, your bond and will cultivate an adventurous spirit that is curious, and not cautious. Like with Bitcoin, or anything new, start small. It’ll be the best decision you ever make!
