A newborn is likely to challenge you in ways you've never imagined. My best advice is to try to find a short project that you're able to take-on and complete before your child arrives to give yourself a small financial buffer. When your baby is born, take some time off. It sounds like you need it, and it's a natural time to set work aside to focus on your family. Also, you wife is likely to need the help.

Having a kid will require you to learn all new things. Sure - they're not tech related, but it'll get your brain to work in ways it never has before, and perhaps give you a renewed focus about why you're working.

If it were me, I'd also be up-front with my wife about what I'm dealing with. You're bound to be sleep-deprived and at-times frustrated with the challenges of a newborn, and it'll help to make sure she's aware of your concerns. Good luck! Work will come and go, and I'm sure a short while from now, Angular will be considered old-news ... but having a kid is an awesome experience.
