M.,
I applaud you for this step. It is a huge committment that can cause a great deal of stress- but also be a wonderful experience. I have worked in the foster care program for years and have a few comments/suggestions for you.
You often will have very little information about the children placed in your home. Sometimes, the placement worker or social worker will generally have very little information to tell you so be sure you ask as many questions as possible and talk to everyone you can right away about the child to see what else you can find about them so you can provide proper care. There is a program called CASA (Court Appointed Special Advocates) that may or may not have a chapter in your community- check it out. They advocate in court for the best interest of the child and they would be a great resource for any foster placement that you have. Talk to the social worker about getting a CASA appointed to the children you have. It gives you one more support system.
Be really cognizant about what the placement of kids do to your own children. I cared for my nephew for a few weeks while my sister in law was trying to get clean and it was just hell on my two young children. The lack of structure and extra attention I had to give my nephew (plus his terrible behavior) really took a toll on my kids. I saw their behavior start to change.
Lastly, you mention how your husband works long hours and it will be mostly up to you- Please just make sure that you still have time for the two of you. I know several foster parents who seperated/divorced not long after taking children in. The added stress sometimes was too much. So, just be sure your family dynamics aren't too negatively affected.
I hope I didn't sound too negative here- because there are so many wonderful reasons to do foster care- but just make sure it is working for your family. Join Foster Parent Associations and network with other foster parents- that way you will have more support systems.
Take care- Please feel free to send me a message if you want to talk more about it.
