WFH is killing my work output and my sanity

Been working from home for 8 months and I feel like I'm doing everything halfway. I'm trying to be present with the kids during the day but also getting emails from my boss asking where the reports are. My home office is right next to the living room so I hear the kids playing and it's impossible to focus. Then I end up working late at night after they're in bed to actually get stuff done. Rinse and repeat. Feel like I'm failing at both work and dad duties. Thinking about finding a cheap coworking space just to have boundaries.
