I have young kids and had less than optimal sleep for years. Anywhere from 2-7 hours a night. It will never be ideal, but it can’t be helped. I would just look at other ways I could compensate. Good nutrition, additional recovery methods, listening to my body e.g. maybe not maxing out the next day on a workout after a night of a few hours sleep. Then trying to balance stress in other parts of my life. It’s not forever and the body can adapt.
