Congrats! I am a father of two kids under 3 and a full-time attorney. It all depends on your priorities and the agreement you come to with your partner, but the days of 10-plus hours per week are probably behind you for a bit once the baby arrives. I’ve found success with getting exercise when I can, how I can. These days that means a lot of 45 minute lunch time runs from my office so that my mornings and evenings are available for family time. If you’re an early riser, that’s a great option too. Try to maximize your off-days with bigger efforts (but give your partner the same time away). FWIW, having my first kid motivated my fitness to new heights – I ran my first 50k – but the second has made obtaining fitness harder than ever. My overall advice would be to enjoy this new time with your child and partner, and be gentle on yourself when you’re inevitably too exhausted to do strenuous exercise.
