The education she is getting through travelling is priceless, don't ever let anyone make you doubt that! In my adventures, I have met a few couples travelling (long-term travelers or short-term expats) with not just 1 but sometimes 2, 3 and even 4 of their children, from tiny toddlers to teenagers. They were all outspoken, open-minded, and genuinely happy children :)
Look forward to reading your future posts!
