First off, Congratulations! Sounds like 2008 is going to be a year of tremendous change and transition for your family.
I'm not sure if this advise is something you are comfortable with or not, but really, in times like these it's my best advise. Pray. Be specific with God and pray for exactly what you want. Give it to God and he will help you. This trouble isn't worth you getting sick, especially when you are expecting.
Beyond prayer, I have a few other suggestions. Be honest with your HR Director at work, and ask if there is any way to change your shift at work, make it shorter. How much shorter can you go without losing your benefits? Remember to say you are just fact finding at this point, trying to plan ahead. Your husband should do the same. Employers value good employees, and most times they will want to work with you. Second, you can go to your county to find out a list of daycare providers within your price frame. Also, there are churches that have daycare that may also offer you a 'scholarship' if you can meet their financial criteria. It's worth asking the question. (South of the river, Berean Baptist)
I hope this helps.
