We will be taking a plane trip across country this summer to visit family and it will be the first time we've traveled out of state with our son. He will be 2yrs + 3 mos at the time of travel and we will be staying for a week. I'm hoping you ladies have some tips and tricks to make this trip easier on everyone. In the car he does alright for the first 2 hours, but doesn't like sitting much longer then that. He is a VERY active child who doesn't do stationary very well. Thanks in advance!
