How did kids change your travels?

My wife (wild to say, just married) and I are currently in Japan discussing how traveling with kids may differ compared to the two of us.

A bit about us, we've been to all 7 continents together over the past 5 years across 15+ trips. We have built (and lucked into) a blessed life and constantly express gratitude!

Further, we typically travel at a fast pace, say ~20k steps per day for ~2 weeks with multiple hotels. Eventually, returning to work restored and refreshed but physically more exhausted than when we left!

Finally, we seek out nature oriented activities in every trip (wildlife viewing, snorkeling, parks) but also love long city days, theme/amusement parks, and sporting events.

So, anyone who traveled like us before kids, what has changed with them? And how did it change as they have grown? Anyone who didn't travel like us, I would love to hear your perspective, too!
