M.B.
We flew with our 10 month old last year to Maine. Our peditrician suggested giving our daughter a dose of infant benedryl about an hour before the flight. We tried flying the first leg with out it, and regretted it. With its aid it made the trip much more enjoyable for all. If your child uses a pacifier, I would recommend that as well as it serves the same purpose as you and I chewing gum during take off and landing. I hope this helps.
