You are avoiding answering a legitimate question.
The question should be more specific: Do you think you have the right to force a mother to give her 19 month-old medication to stop him from saying, "Bye, bye, plane"? Those words are so disrupting to you that a small child should be drugged asleep so that you don't have to hear them?
As far as I could tell from the story the FA never attempted to force the mom to give her child any medication. Also, Fox News has been carrying reports that the child on several occasions interrupted the FA's giving of the safety instructions.
From the mom's use of the word, "bubbly" to describe her child I strongly suspect that the child was doing more than simply in a nice sweet baby voice, saying "bye, bye, plane". Back that up with the child's behavior on GMA, and one just has to suspicion that there is more to the story than is being told.
But at any rate at well over 300 posts I think this thread has become tiresome.
Hey, you're the one who resurrected it. :-)

Yes, it's a legitimate question, but it would take too long to type a response. To make it more specific:
Where do you consider my rights to end and yours or your child's, to begin if we are both passengers on the same flight?
The same as with any other type of public transportation. Unless the airline adopts a no-talking policy, every passenger has the right to talk. Once I got stuck next to a pilot who talked about himself through the whole flight when I really just wanted to sleep. Did we taxi back and boot him off because he was disturbing me? No. One exception would be making a threat to someone else on the airplane, but no one has backed-up the flight attendant's story that a threat was really made.
OTOH, no one should be making unwanted physical contact; that is, someone else's child shouldn't be jumping all over you while you're trying to sleep. And children should be controlled within reason; that is, they shouldn't be running up and down the aisles which, for one thing, would be dangerous.
A good policy for the airlines to adopt would be separate business flights and family flights. That way, you could avoid children if you like. But that's probably not feasible financially for the airlines.
