||Life won't ever be the same again, and I mean that in the best possible way. Although, I can testify that the first few months of sleep deprivation are a blur.
Even with the young'un, you'll still have time to enjoy the car. Dedicating time to work on it may not be what it used to be, but honestly, that won't hit to too hard until you have #2. I'd actually hold off on any major work until you get back to a normal sleep pattern. I don't know about you, but working while tired rarely ends well.
Congrats again, bud!
