Hi D.,
I don't have advice from the foster parent's perspective, but I am a social worker who works with foster parents. I can tell you that good homes are needed for foster children as there are never enough homes for all the children in out of home care. However, that does come with a lot of responsibility, exposure to tragedy and hurt that you may have never experienced or even imagined could be true and you will likely become extreely emotionally involved with these children and it will be difficult on all of the family members when the children leave. On the flip side if these children do not return to their parents you will be asked about your interest in adopting them. Another thing to keep in mind is that a lot of the children in care come with psychological and behavioral issues and therefore often have appointments, such as therapy, speech, and medical visits. In addition to that most of the children have visitation with their parents at least once or twice a week (and in some cases more) and you may be asked to monitor these visits which means a new level of responsibility for you as well as taking time away from your own family. My hat truly goes off to all of the foster parents out there. There really is so much to say about it that's it's hard to encapsulate here for you. I would suggest that you attend an orientation. You can either work with your County public agency (Social Services) or you can go through what's called a Foster Family Agency (FFA) which there are numerous agencies out there. The difference is that with the County you are a licensed home and with an FFA they hold the license and certify you. The FFA can provide a higher level of support than the County typically can, however that also comes with more responsiblity, such as attending mandatory trainings and typically meeting with an FFA Social Worker 3-4 times each month. Which is in addition to the County Social Worker who you will typically see one time each month. Also if you have multiple children who are not siblings you may have different County Social Workers for each of those children. I don't mean to overwhelm you but want to throw out some of the things you should consider before proceeding.
It's a difficult job, but those who do it for the right reasons make an unbelievable difference in the lives of abused and neglected children. Your best bet right now to learn more is to attend orientation with different agencies and the County which will give you first hand info. about what is expected of you as a foster parent and this will also give you an idea of what you feel comfortable with. The last thing I would caution is to make sure your family is in a comfortable financial situation as you do receive compensation, however it will cover basics, but not extras such as school trips, extra curriculars and that type of thing. Good luck and enjoy whatever choice you make!
