Bbcoach gave some great advice as well as others - God's guidance and you have multiple options. 6-Active and 22-Reserve with USN for me and now have a pension and medical to look forward to in a few years! Like others, took about two years to figure out I no longer had to drill or put on the uniform.
Just like when you're ready to retire, you'll know when it's time to get out or even change careers in civilian life. You have 18-months to get out of the military all you can such as college credits, extra course work, transition benefits, etc.. if you do decide to leave. Best of luck with your decision and congrats with your first child on the way; November is a great month to be born!
