We just got home from our first flight. On the way there I nursed her as we were waiting for take off and she fell asleep while we were taking off. She slept most the time and woke up so happy. Nursed her on the landing and she was great.

The flight home was kind of a wreck. She didn't know what she wanted and cried for a big chunk in the middle then finally fell asleep till we got home.
I packed some picture books and a couple of toys. this sheep was what put her out on the 2nd flight.
