I made this for the boys before our trip, thought it might be helpful to share.
New experiences, however fun or exciting, can be really stressful for Cuddlebug and Bearhug so the goal of this was to walk through what to expect step-by-step. With flying, I knew there would be a lot of steps involved and wanted to help them transition as smoothly as possible from one area to the next as we went through the process of getting checked in, going through security, finding our gate, waiting, boarding, etc. The fewer surprises the better :).
I put the pages together in powerpoint and then printed them out with each slide taking up half a page. Then I cut the pages and stapled the edges to make little booklets. They didn't actually spend a whole lot of time looking at the booklets but having thought through all the steps helped me to be prepared to talk them through everything as we moved from one step to the next.
If anyone wants the .ppt file so you can adapt it for your own family just send me a note or leave a comment, I'd be happy to share it.
