How do I keep my kid from acting up when traveling by air?

If you give your child a dose of benedryl this will calm him/her down and maybe even let him/her sleep. But this is only if you do not have any problems with giving your child an OTC (over the counter) medication. It is not excepted by all the masses and I will probably get a ton of hate mail for even suggesting this but I do know from personal flying experiences that a sleeping child is greatly appreciated by the fellow passangers.
