I have traveled a bit. Visited maybe 10 other countries. Lived in Russia for a few years. I would not give us that experience easily. It changed me and helped me understand myself and others better. I would recommend living somewhere foreign, but not tourist-y big cruise-ship style of travel. That doesn't change you as much. If you really want to travel, try studying the history and language and staying in the country for a little while so you understand the place better.
However, I would give it up all of that experience for my kids. If I had to pick travel or children, I would pick kids. They changed me more than traveling did. They give me a different outlook on life. They make me a better person and happier. I like kids more than traveling, although I hope to travel much more when the kids are grown and leave the nest.
It sounds to me like you are unsure whether to travel or have kids. To quote the Cheshire cat from Alice in Wonderland:
Alice: “Would you tell me, please, which way I ought to go from here?"
Cat: "That depends a good deal on where you want to get to."
Alice: "I don't much care where –"
Cat: "Then it doesn't matter which way you go.”
