Here we go again. Please explain to me how just because women do something that is about as regular and expected as possible like having a baby, that they should somehow be exempt from rules and preventative measures to assure that not everyone is disturbed by what is inherently as psychotic asshole of a human as we get. A baby doesn't care that hundreds of people have paid significant money to attend a presentation by an expert in a field, which is also being recorded and will be distributed around the world in hopes of educating people far less privileged that said baby. It is not unreasonable to not allow any human that cannot be respectful of others around them. Unfortunately, babies are kind of assholes that don't give a shit what you or anyone else around them want.
Providing childcare on site would not affect the conference experience of others.
What's next? Banning people with mental disabilities from conferences/anywhere else really because they might inconvenience you? Banning disabled people because they might require more space and block your view?
And what the f* are you even talking about here?
"in hopes of educating people far less privileged that said baby."
