You know, I am a single mother of 3 children, and I have had to depend on my family alot lately, now that the "daddy" is back in jail again....
...all I can say is love your children and try your best, only buy those things that you absolutely need and try not to give in to temptation. It will be hard but you can do it, just set aside as much as you can when you can and when the baby comes, you will be surprised at how much you have saved.
I am now on my feet again after my third (yes third) c-section only 3 months ago, and I am about to go back to work. Thank god my mother has been here for me. You can do anything when it comes to your children. Try calling your debtors and let them know what is going on, believe it or not, some people can be sympathetic and you might get extentions or budget billing for some things. Just don't go about it thinking that you have no options.
OH, and about the child support, you can file now at the department of revenue, (child support enforecement) they can set it all up, then act on it when the baby is born.
Best of luck, I know it's not easy.
