Practising at 4.00 - 6.00 a.m., or late at night? If I lived in the same household, personally I wouldn't exactly welcome being woken at times I was normally asleep - even if, otherwise, I liked the music. And if I had to do homework or other things, background music would be highly distracting. I can only read, write, or focus on anything at all really, in the complete absence of music, no matter how soft. And I do wonder whether lots of people who live with a musician get heartily tired of hearing the same passages played over and over dozens of times, day after day. I know musicians have to spend long hours practising; but I would find living with a musician quite impossible. (I have lived alone since the age of 17, which was over 4 decades ago.)
It's a difficult problem if you live with other people. I realize it's totally useless advice to anyone who has already started a family: but I have always thought that it would be wise for anyone seriously wanting to dedicate themselves to music or other arts, or maybe anything in which it's very difficult to earn a living, to really consider whether having a family would be compatible with that - unless one already has lots of money, when one can buy various items or services to *make* it compatible: help with household tasks, housing space, whatever. Pursuing an artistic career is very demanding and time-consuming, and probably money-consuming too; but so is raising a family. The question is whether most people can do both of these adequately and to a high standard. I suspect many can't, and the attempt to do both may for many people cripple both activities to some extent or other. (Disclaimer: I have never married nor had a partner nor had children - so maybe my point of view is somewhat biased. But that's how I see it.)
