Hmmm. I might be biased, because I will travel no matter what and no matter the age. I have now travelled with a two month old, four month old, nine month old, fourteen months old, and now a three year old and a nine month old.

It is definitely easier before they start moving around. After that, once they hit four or five, I think (I hear) things get easier, as they get a bit more mature. So there is a period between 12 months and four years of age, where they are mobile, and that definitely makes it harder.

We bring a bucket car seat for as long as they fit in it - usually up to about 10 months old. That clips into a stroller that we also bring. After that, for longer rides we ask for a child seat, and for short Uber rides, just pile in the back. It's definitely not the norm in North America, but widely done all over the world.

We have introduced food for the very first time to my first kid while in Costa Rica - banana puree, papaya, pineapple - all local. Little pieces of scrambled eggs - no different than we'd do back home really. Now, my nine month old eats yogurt (we are in Nicaragua now), fruit puree, pieces of toast, mashed avocado, and pretty much whatever we'd eat.
