1 year olds can eat a very wide range of foods as long as they’re served right so it wasn’t an issue.

Car seats and strollers are gate checked (different imo) at most airlines

The chance of a gate checked item getting lost or forgotten is near zero in my experience

I went to Disney for a week with my 1 year old and wife. We used 2 carry one and a personal bag.

I refuse to take checked bags because I travel off and on for work and I’ve been burned too many times with checked bags.

It’s pretty easy to pull off if you just do things like sleep in the clothes you plan on wearing the next day or only bringing enough diapers and wipes for the plane and buying a weeks supply at your destination.
