Owen's first flight

We made it to San Diego. We had a good start, as you can see from the first picture! He slept in the car and was pretty happy checking out the airport. You should have seen us lugging around all our baby loot. He did so good until the plane took off. Once we started going up he started screaming, he cried harder then he has ever cried. I think his little ears were hurting. It took a while for him to calm down, but once he did he fell fast asleep. Then I cried. It was sad seeing him so upset and not being able to help. He was back to his normal self as we were leaving the plane, smiling at all the people and getting lots of smiles back. He got to see Grandma and Grandpa Worcester and Uncles David and Andy tonight. 
What did you do when flying with an infant? Any helpful tricks to try on the way home?
