There should be different sections on an airplane: mothers with cryin, babies section, obnoxious drunks section, gamey passenger section, snorers section and for the rest of us, good looking people section. Those that pass gas should sit with the gamey ones who should sit with those that wear too much cologne or perfume so that they cancel each other out. Just MHO. In all seriousness babies cry for many reasons and not always for reason that are under the control of the parents or care givers. The change in pressure can cause excrutiating almost unbearable pain to some of us who suffer from sinus problems; I can only imagine what it would be like for a baby who can not express what they are feeling. Free cocktails for everyone (including the toddlers) might resolve the problem and then may it would  or  exacerbate the problem. Then you would have an airplane full of snoring, stinky, gas passing drunks. But then again maybe no one would care. 

 Ed ! As funny as it sounds , you have a point !
