Sightseeing with kids in Rome? The bad news: Because of their skew towards art, history, and archaeology, some of Rome's sights can seem less than immediately child-friendly. The good news: There's enough here to keep kids entertained and happy. If you do it right. Truly.
Here are some things to keep in mind if you're sightseeing in Rome with children.
1) Make sure you don't stand in any lines
Kids hate standing in line as much as adults do. They're just (usually) worse at hiding it. So make sure you avoid the lines at the top sights. At the Colosseum, use a RomaPass or get your ticket at the Palatine or Forum entrance; at the Vatican, cough up the extra €4 (yes, per person) and book your Vatican museums tickets in advance.
2) Know the limits of thy stroller
I've said it before: Rome is a city best explored by walking. That might be fine if you have a super-energetic 10-year-old. But traveling with a toddler? You'll definitely want a stroller.
Just bear in mind that Rome is a city of cobblestones and ruins. Translation: Any stroller you bring should have nice, sturdy wheels. It should also be light, because you'll sometimes wind up having to fold it up and carry it—at the Colosseo metro stop, for example (there's no elevator, just stairs), or at your B&B or hotel (many have tiny elevators, or sometimes no elevator at all).
Also keep in mind that you won't always be able to use your stroller. They're forbidden in St. Peter's Basilica, for example (you can check them before you enter). So it might be a good idea to also bring a backpack child-carrier.
One thing not to worry about? Getting strollers on and off buses and public transportation. Yes, it can be daunting—but you'd be surprised at just how many strangers will help you with the task.
3) Hit up sights children will love
I promise that they exist. Some favorites:
Palazzo Valentini makes ancient Rome come alive in a way I haven't seen in Rome before; because it's very dark, which can scare little ones, it's best for ages six and up.
I haven't done this yet myself, but at Gladiator School, kids (and adults) can try their hand at being gladiators, donning their tunics and duking it out with foam swords. Talk about making history hands-on. Apparently, even toddlers can participate.
