My son and I used to take these books and it helped. He does not need it anymore as he is fluent now. But we used to pack them on all trips.

When he was younger, I used to seat him on top of my car. It used to be fun for him to lie flat on the car and watch planes approach overhead.

There are several nice spots around JFK to do that. Or at least there used to be.
