What items do you all bring along for overseas travel with a 5month old baby? TIA!

This is a super interesting article about travelling overseas with a baby below one years of age. http://www.lisamckaywriting.com/20-tips-for-traveling-overseas-with-a-baby-under-one-year-old/ Some interesting points she brought up (besides the basics) include bringing the usual clothes that baby would sleep in. Young babies are creatures of habit and having their usual things especially during bedtime will help them settle down better in a foreign location. Another interesting point would be letting baby crawl and play as much as he wants during a layover (be it long or short). Burning his energy before the next flight will help him sleep better and longer on the plane.
