I'd try a different tactic if I were you... screaming at a crying baby just makes it scream louder. They're babies, you see.. even at the advanced and mature age of 12 months, they are not quite up to speed on etiquette. It's a pain, but there you have it.

Doesn't mean they can annoy their surroundings like hell and get away with it.

And it may incur the mother's wrath...not a good thing, as this lady discovered. ;D
If the mom was a good parent she would have made it shut up after the first complaint.
Are you in for a shock when you decide the time is right to breed. 1 year olds do one of three things:
Sleep
Sh#t
Cry
And they can do at least two of these things together.

That might be true but any decent mother would not ignore a crying child anywhere, never mind in a public place. This is becoming very common & I find it both upsetting & annoying. I wouldn't mind so much if they made some attempt to comfort the child but they simply ignore it. No wonder the poor mite is bawling its head off. Makes me wonder how they go on at home. Unfortunately it's quite likely that those children will grow up just like their pig-ignorant parents.
I'm speaking as a proud parent, now going through it all again as a grandparent. I'm pretty tolerant these days, especially where young children are concerned. However, I get a tad fed up listening to the constant whinging of a few inconsiderate people's children when I've always done my best to make sure my own do not disturb anyone.
