If u lost your job already, u didn't choosingly give up a stable(don't know u, so guessing) job as the other person alludes (don't know their situation so people guessing here).
So if u had a stable good paying job, giving it up to start something new while having a new kid can be very hard .. but doable. Still I'll advised.
If u lost your job, based on job market, career switch makes total sense as you need to help provide and a career switch may provide a better or stable opp.
Many people have successful home life/family life with no financial stability or even a job altogether...
that's true, and also why it's prudent to not go around giving unsolicited family advice to strangers.
also it's why, when you're talking about one particular woman you've never met, you should keep the demographic insights you think you have about her to yourself.
Healthy and stable relationships sre built on care and being good people, not what you're job provides.
