I agree that it you want a baby more than nearly everything else, you should have a baby.
But "wanting it more than nearly everything else" means you want it more than you want to not live in a mediocre-at-best studio apartment, and than you want to not eat beans and rice 5 days a week, and to not drive a 2008 Toyota Corolla with a dented door and broken radio, and to not eat any meals out pretty much ever, and to not exchange gifts with family for holidays and birthdays, and to not have cable, and just about everything else.
So, do you want a baby that badly? If so, great, go for it. But then be the responsible adult and give up all those other things to. If you can't then clearly you want those things more than you want a baby, which is fine, too. You can responsibly have whatever you want. Just not everything you want. So pick what it is you want, and then readjust everything else to align with that priority.
It is grossly irresponsible to choose the kid but then not do pretty much *EVERYTHING* within your power to get your finances in order. And "in order" means not only addressing the debt, but also addressing future spending, and building up a substantial emergency fund, all on top of being able to pay for childcare and other expenses, and additional time off for days she is sick (if you don't get PTO) and other possible work implications of having a child that often needs care and attention during the workday. That doesn't mean it is grossly irresponsible for you to have a child. It is only so if you aren't willing to make the other sacrifices in order to get what you want and still have your financial house in order. From the sounds of it, it is going to take some extreme sacrifices for a few years, all while you want to be adjusting to new motherhood (at time during which you are likely to often want to throw money at problems when you are sick, tired, unappreciated, exhausted, and stressed). For you, just ordering in or going through the drive through, or not shopping thrift because it is faster than a trip to Target, or wanting to pay a housekeeper for even just one time because you are exhausted and can't deal, or wanting to hire a lawn service, or whatever, are not going to be in the cards. Unless you want to be irresponsible, have your child grow up in financial uncertainty, and never get ahead.
So, if you want to do it, do it. But know what it will cost (and I don't mean just the numbers), carefully assess that, and be honest with yourself when deciding if you are truly willing to make those adjustments.
