Suffer is a good word for it. Nothing worse than being in a public place and having to put up with someone else annoying brats that won't shut the fsck up. I say we ban kids from public places... as a bonus you'd never have to deal with seeing breast feeding because there would be no kids around to breast feed!!! Maybe that's a bit extreme, but I'd be all for having designated "kid" and "no kid" areas in public places, just like they used to have with "smoking" and "no smoking" areas.
