Yes there are some asses out there who can't tell the difference between a necessary trip like leaving Africa where having small children would be acceptable and an unnecessay trip like visiting the grandparents
I am 57 and have crossed the country more times than I can count, the Atlantic 18 or 20 times, plus trips into Africa. Baby's are a part of life and flying has become common, it is not for you to say where they can go.
Until they were 6 or 7 I would never take mine into a fancy restaurant. For years it was pizza, Mexican food and spaghetti restaurants. I didn't want to bother others, but flying is a different matter.
OH and I took my first flight at 3 months, from Houston to Baltimore where dad played for the Colts.
So, according to you, a kid shouldn't be able to see his grandparents until he's what, 10? 12? What's the proper age?
