Remote work dad life is hard to balance

Working from home since my youngest was born and it's not the blessing everyone says it is. My boss expects me to be available same as before but my kid needs me during the day. My wife went back to work too so I'm trying to work and watch a toddler. Doing neither well. Took a call with my director and my son was screaming in the background. Felt like I failed at both jobs. How do other guys make this work?
