Remote work with a 3yo is destroying my productivity

So I've been WFH for about 8 months now and my company is cool with it, but holy hell. My son just turned 3 and he's in daycare 3 days a week. On those days I'm golden—actually get my work done. But the other 2 days when he's home? I'm running on fumes.

Today I had a client call and he literally screamed "DADA DADA DADA" the entire time. I had to mute. The client knew. I could feel it.

My wife works standard hours so it falls on me to watch him those days. I've tried the whole "quiet time" thing, iPad, whatever. Nothing works for more than 15 mins. Anyone figured out how to actually make this work or am I just supposed to accept my career is gonna take a hit for the next few years?
