Is it easier to travel with a baby or a toddler?

Most people have found that traveling is a baby is much easier.  This is largely because they are not yet fully mobile and haven't learned to walk or run just yet.  Babies are considered infants under the age of 1.  Traveling with a baby or a toddler still requires a lot of "stuff", but babies are typically more easily entertained by everyday random objects, such as a cup, or a napkin, etc, whereas toddlers are further along in the developmental journey and need more stimulation, especially on a long journey.  Babies are also small enough to wear in a baby carrier, leaving parents hands-free to be able to juggle the copious amounts of luggage and toys needed when traveling with little ones.  Babies are typically easier to travel with on planes as they still sleep for more hours than they're typically awake.  According to many studies, the ideal age to travel with children is between 4 months to a year.
