婷婷OK la. We had a trip of 17 hrs. (4 hrs wait for transfer) flight together. 婷婷 immediately slept for three hrs soon after she got on the plane. I don't think you need a DVD player for your kid. The battery won't last too long anyway (bring more battery). I did not bring any toys at all and she did fine. She thought the airplane and flying are great. Wish you a happy trip
