I loved the title of this article. Traveling with Multiples is quite an accomplishment (especially when they are really little) but the benefits of getting your kids accustomed to travel early on are great.
The struggle I have with my twins is whether or not to put their car seats right next to each other (helps with passing toys, watching movies, etc.) or keep a reasonable buffer between their seats (to avoid, hitting, pulling, taunting, etc.).
