Remote work with 3yo is destroying my productivity

So I've been WFH for about 8 months now and honestly it's gotten worse not better. My daughter just turned 3 and she's at that age where she NEEDS constant attention. Our daycare is only 3 days/week because we thought this would save money, but I'm basically working from 6am-11pm now trying to get stuff done when she's asleep. My manager thinks I'm slacking because my response times have tanked. Anyone else dealing with this? How do you actually focus when there's a tiny human demanding snacks every 10 minutes?
