Hi J.,
When I flew with my daughter when she was an infant the best advivce I was given was try to have her suck on a bottle or something during takeoff. This will keep there ears from clogging. Since my daughter was breastfed for 16 months it was kind of hard to get her to suck a bottle but if you child does that is great. It really works. Hope that helps, hope you have a relaxing flight.
