K., this is my first post since I joined the mom's group last week. I don't believe there are rules against single foster parents. If you've shown that you have a stable family, supports etc that you probably would be considered. Only way to find out is to call DCF and ask. A Social Worker would be happy to answer any questions you might have.
In your search bar type in the following:
Department of Children and families CT
It will bring you to their website. Lots of links to view. Many rules and regulations to go through such as every member of your household has to have a physical. Water tested, check for lead paint,back ground check etc. Once these things are taken care of then you would be all set.
It's a worth while investment of your time. I know that foster parents are hard to find. If your capable of doing it, your children don't mind a stranger coming to live with you and then have to leave maybe days or months later, your family supports you, then GO FOR IT.
