Air travel, kids, and throwing up.
I will not name names but both daughters have upchucked more than once either before flying or inflight.  And I say this because some other kids while flying seem to be okay with air travel.  Meaning not throwing up.
But there was this one time at about 25K feet up when my daughter alerted me she was not feeling so great and about to barf.  So, we go into counting backwards from 99.  99, 98, 97, etc.  Are you following me?  If she skips and number or repeats a number then she must go back to 99 and start over again.  Got it?  Hopefully taking her mind off puking.  In the past it sometimes worked and sometimes not.
However, on this one flight we seemed to make a landing without grabbing the airline supplied barf bag.  But it was just one stop away from our L A destination.  One more takeoff and landing.  We had about a twenty-minute stop before taking off again.
Therefore, we were feeling much better while grounded.  Then the kindly flight attendant ask daughter if she wished to go with and three other kids her age and get some pizza out in the waiting area.  So, she gladly went and enjoyed a nice pepperoni pizza and then they all returned moments before taking off again.
In retrospect it was the take offs and landings that prompted wobbly stomachs. 
Then it started again on lifting off at the end of the runway.  ‘I don’t feel so great” indicating to me she might certainly bring it all back up.  When she begins to moan and groan I  know something is about to happen.  Then I grabbed the convenient airline logoed barf bag, open it out, and placed near her groaning mouth.  Plus, the same flight attendant grabbed a larger plastic garbage sack and placed just behind the paper barf bag.  And sure enough all that free pizza came back up and well captured by myself and the kindly flight attendant.  The very same attendant who suggested to go get some pizza in the first place.  Thank you very much Ms. Southwest.
