It's harder up until they're out of diapers and car seats. Thankfully, it's a lot easier than it used to be, especially with food delivery and uber-like services everywhere. Use AI if you want ideas, and google translate to read menus and signs, airalo (and some bitcoin version, too but I forget) to get e-sim data for whatever country you're going to cheap.

There are definitely downsides to traveling with kids, like cost and having to accommodate their tastes, but there are upsides, too. You get a lot of discounts, for example, especially at museums and such in countries with few kids (like Japan!) It's also fun being with them and giving them memories. A picture in front of some iconic place is a lifetime memory. It's also really good for them to get exposed to different cultures.

Anyway, it's going to be harder, no doubt, but it's also more meaningful because you're doing the activity as a family. And don't underestimate how you'll look back on it. A trip like that is something that you'll be referencing for the rest of your life.
