Foster to Adopt in MI, is an infant/toddler possible?

thank you both for the info. We are going to meet with an agency that places foster children soon. We are kind of undecided right now about the "emotional rollercoaster" part. I think if it was just my husband and I we would be more certain about going for it, but I have a lot of concerns about how well our daughter would do. I anticipate we will ask a lot of questions about that. If we had an infant/toddler for a while and then they were reunited with their birth family I anticipate she would be heartbroken. Any ideas on that part out there? A friend of a friend recently told me that they adopted through foster care but insisted through their case worker that they would only foster children whose parents had already had their parental rights terminated. She said it was to try to get around the part of having a lot of foster children that then are reunited and explaining this to her remaining children. Any experience with that idea? thanks again for the ideas everyone.
