Must-Have for Baby Travel Gear

Since we have family in different parts of the country, traveling is a must for us, so I am always looking for products that might make the trip, or being away from home, a little easier.  And I have to say the Go-Pod (pictured) was the number one product this summer for our vacations to see family and introduce our new little one.  This portable, lightweight activity seat folds up easily – a must when packing up the family roadster – but it is so convenient, I use it every day around the house as well. You can read all about it here, but I want to know, what was your must-have product for travel this summer, for your babies or young children?
