Traveling with an Infant

We are traveling with our son for the first time this week. I think we could spend $1000 on all the items that are available to make traveling with kids easier... it almost makes you wonder if buying all that stuff will make things more complicated because it is just more stuff to keep track of.
Car Seat Strap
However, I did restrain myself and only purchased three items. A cover for our car seat (we are checking), a cover for our stroller (we are gate checking), and a strap to go around my suitcase the the car seat attaches too. I will let everyone know if these made thing easier!
