I've been there. In the first property I owned. Over 40 years ago.
I travelled a lot. So obviously the flat was completely silent, when abroad. But everything I did, when home, including running a bath, irritated them.
I did talk to the neighbours. Because I'm not a loud person. And I am polite and respectful.
I pointed out many things, including their advantage I was absent 50% of the time.
However, I also pointed out my rights, including socialising, which could further impinge on their peaceful enjoyment.
It was in no way confrontational. The aim was, how could we live together.
The one thing that became obvious was pre-knowledge and expectations.
I let them know when I would be abroad, so they could make the most of my absence.
I let them know when I would have a social gathering - so they could go visit their children.
So just suggesting - you let your neighbour know when your child is starting school. You drop through the letterbox the term times and holiday times. You let them know when you're going to be away.
Just keep them informed.
You're maximising their ability to work around your noise.
But if they know your routines and expect noise at certain times, people adjust.
