The only entitled person here is you, who somehow thinks that the rest of society should bend over backwards to accommodate you.

The thing is, if you want to use public transport you have to accept that other people are also going to use it, often at the same time, and some of those people will happen to be babies, who are a normal part of society.

If you don't like that, then either buy a private jet, or get over yourself. You were once a baby, we all were. And I'm sure you cried sometimes just like everyone else. It's just a normal part of life :)
