As the dad of a kid who had terrible colic when we lived in an apartment, I sure am glad nobody called the cops on me.
We had twins.
One of them was always awake. They seemed to take shifts sleeping.
The first year of their lives was an unholy terror that seemed to last five years. It wore us to a frazzle.
My folks would come visit and keep the boys for a weekend every two months.
They would stay at our place with the boys and we would get a motel room and sleep the entire weekend.
That is the only way we all made it through their first year.
Thankfully our downstairs neighbor was a widower, retired army non com who didn’t let anything faze him. A really good guy.
I don't know whether there are practitioners in the USA. We were living in Belgium at the time and, being in an apartment building, our neighbors weren't shy about complaining over the noise. But it was a revelation that something like that could be done.
