If it's not possible, then I suppose you'd better not take your 19 month old child on an airplane. That's why God invented the minivan.
If you can't deal with the public, that means children included, charter your own airplane and you can have all the peace and quiet in the world. If you don't want to spend the money for the charter suck it up and deal with it. People with children have just as much right fly as people without little ones.
