I only have one kid, but similar situation for me.

I learned something about jobs during this time. The effort and stress involved is not proportional to the pay. Some jobs are just hell and you can go next door and make the same thing in a pleasant environment.

I ended up taking about half my skills off my resume. I'm no longer a full stack dev, I'm a backend engineer. I removed the stuff about DevOps and project/product management. Then when interviewing I found a role that paid the same as my previous job but required me to only wear one hat rather than 5 of them.

Life is much better now.
