When I was 25, I quit my job and went on an open-ended tour that ultimately lasted 14 months and took me to 3 continents. 6 of those months in the middle were mostly not touring. I didn't own a home, didn't have a partner, and most importantly, didn't have kids. I had an idea of what I would do when it was over, and that worked out.
When someone decides to have kids, they're making a commitment to feed them, provide shelter for them, educate them, and protect their health & well-being until they become adults. I'm wondering if the OP has thought through how they will provide all of this for their children both during and perhaps more importantly, after any travels?
