Remote work with a 3yo is basically impossible, right?

So I've been trying to do my job from home while my son naps and after bedtime, but our daycare is closed Wednesdays for staff training. Yesterday I had back-to-back client calls scheduled and my kid decided that was the perfect time to have a meltdown because I wouldn't let him eat dog food. I muted myself for 10 minutes and just... sat there. How do you guys actually make this work? Do I just accept that I'll be in meetings at 6pm forever?
