Same boat, my son was born in October last year and have been back at work since February and I am already completely overwhelmed. Our plan is to wait for the second child and get another paternity leave and then I will fuck off from any corporate/enterprise job and try to do my own thing first and we'll live off menial jobs + the income from the couple of apartments we have on AirBnB.
I am not planning to stay out of tech altogether though, at least long term.
