I don't know much about the debt consolidation, but bankruptcy seems like an extreme measure to me. If you contact your student loan administrator, you could probably get a financial hardship deferrment for a short period of time. I did that with my student loans when I lost my job several years ago and was able to resume payments when I got a new job with no long term financial detriment. As for the credit card debt...you don't say how much of that you have, but I do think that Financial Peace University could help you with that. If you take it through a church, it usually costs nothing except for the cost of the book and most provide childcare. My husband and I had a lot of credit card debt when we got married because we both had some from college and used credit cards to pay for some of our wedding expenses. We spent the first 3 years of our marriage scrimping and paying that off so that we would be in good financial shape to start a family. It took a ton of discipline on our part, but it can be done.
I am a firm believe in the fact that if you wait until you are completely ready to have a child, you probably never would, but in your situation, I feel like it's a little irresponsible to bring a child into your home when your financial situation is so dire that you are contemplating bankruptcy. Take a year or two to really buckle down and get your debt under control and then think about another child if your situation is better. Think about things like going to Starbucks or eating out (even fast food). These things consume a ton of money that doesn't seem like a lot at the time, but can really add up. Cut back on unnecessary expenses (reduce cable to basic, cut down on your cell phone bill by eliminating texting, web, or other options that aren't necessities). Every little bit counts if you use that to pay off your debt. Again, these are things that you could learn through Financial Peace University, so I won't ramble, but you really have to be serious about change if you want to make an impact in your debt situation. Best of luck to you and your family.
