So we just went to Puerto Rico for a week on vacation and this was our first flight with our 1yr old. We rented a condo so that we could have a little freedom for Eric and be able to cook and wash clothes as necessary. I was thinking that I would post some of the items that I used while on vacation that really were great and necessities for us when traveling with our toddler.
First is this travel seat Portable Travel Seat by Cozy Cover and it retails for $20.99 on Amazon.http://www.amazon.com/Cozy-Cover-9001-Portable-Easy/dp/B00IHIENS2
This seat pretty much fit all the chairs that we had. It was a bit tight on really high back chairs but we didnt have many of those on the trip. The chair folds up pretty small so that I just had it in my diaper bag in the event a restaurant didnt have a high chair which most did. Our condo didnt so we used this to feed him while there most of the time. I would highly recommend this seat for those that travel and need a small compact chair for your little one.
