That's exactly why you should remove sources of stress.

If you are financially somewhat comfortable (I assume most people in tech are so, more or less), it's better to go independent.

The first few months you will be so busy and stressed out not only from the baby but from the wife too, specially given the possibility that OP is not on good terms with the mother of the child (not even sure if "wife").

Imagine being bossed around not only by your boss at your job that you are apathetic towards, but also by your wife, and obviously by the baby?

Resentment will grow.

Better be in control of at least one thing: your career.
