I hate screamers,, to include little kids.
Problem is, in some instances the parents can't prevent the problem.
Case in point: My daughter flew down this Spring with the 2YO E. When she met us at the luggage claims, she and E were both in tears.
E had screamed all the way down. S was not only mad & embarrassed, but completely at a loss as to a solution.
E was diagnosed with a hearing problem and had tubes installed in both ears. The procedure was successful and happened about a month before they came down,, with the Doctor's consent.
Evidently the planes pressure system was not working well and the child was in pain. S thought she had preempted the problem with a children's benadryl an hour prior to take off,, didn't help.
Fortunately, the trip home E was back to smiling & giggling as is her passion..
As far as in restaurants and other public areas.. The parents lack of supervision and failure to maintain some level of control is responsible for 90% on the "problem" child's behavior.
Even if the child has a very valid medical problem, forcing the general populous to endure the problem is not acceptable.
SO,, YES,, kick'm out....
