How to survive a plane with a 2.5 year old

We are about to embark on a 5.5 hour flight with a very busy boy. We are lucky we found a direct flight within our budget but the only direct flight leaves at 9am. Ideally an overnight flight would be best for us as there would be hope of sleep. Trapping an energetic 2.5 year old in a seat for this long brings waves of panic. So we need to be prepared. 

Most importantly we are armed with a new computer for him that is a treat for him to use especially for long periods of time. We are hoping this will keep him busy for a couple hours. Back up plans include trains, colouring books, water wow and lots of snacks. Wishfully I have packed a blanket in the hope he will nap. Wish us luck and I’ll report back on how we fare. 

 Any last minute tips or tricks are welcome

And in case you were curious here’s most of the clothes I packed for a week in Tulum!
