Thanks for owning your past, it is a sign of maturity.
Congrats on having a baby! As for the logistics, you can definitely hunt this tag by yourself (or on your terms). I'd lean on grandparents (or the new aunts and uncles, or your wife's friends) to take some time to visit for a weekend or even a week at a time to help with the baby and keep the new mom from feeling isolated. I have 2 little kids, and the best way to deal with the conflicting responsibilities and your hunting passion is to lean on family. After 30 days, things get much easier with the baby, so I'd plan on hunting the second half of the season, but also any time, even just 2-3 days at a time whenever you can get someone to stay for a weekend. Also, find some people to help you find sheep so you can take advantage of the time you do have. It always breaks my heart when people give up hunting when they have kids when they definitely don't have to.
