Wow, those are some big issues. I know that you can make the best decision out of it, but I can see how that would really require some major thinking. On the one hand I can see that you're just so close and paying for it later may not be possible. And it is important to consider your extended family, especially if they made a contribution. And of course, this is hard, but you can't get back the time you spend away from your DD. But, you will have the time together in the future. I think in the end it can be ok, your plan for afterwards sounds wonderful. And even if you don't use your degree for a while, it won't expire, you'll always have it.
I'm not really being helpful, just empthizing.
I do have a suggestion (I didn't read what everyone else said, yet, so perhaps I'm being repetitive.)- I suppose you can't renegotiate your scolarship, but it may be worth a look, but I suppose that's what your counselor already told you. (but, she has no right to place judements on you about when and how you choose to start a family, you can see for yourself that it's been wonderful and had it's challenges, shame on her). I don't know what DD is doing during the day, perhaps staying home w/DH? But, you might consider day care near campus. My college has a day care center. You could see her during the day between classes. The state may have some programs to help students with children pay for day care.
I don't know if this helps at all. I wish I could provide some helpful information. I think the bottom line is to do what you feel is best for you, your DD, you DH, your little family itself, then your extended family and those who helped you thru school, so far. In the long term, you are the one that has to live your life, and while you have obligations to others, you have to make the choices that will be best for you first, that is the best way to honor obligations others have made to you for your sake.
last thing: if you were taking a poll, I'd vote for finishing school. I think everything can sort itself out afterwards. But, it's not my life, and I only know what you've writen here. You're a young person and you've got your whole life ahead of you and your young family. Who knows what the future holds? You're obviously a dynmic person, and I'm sure things will work out as you want them to, either now or later.
