In some states, fostering is not necessarily the same as adopting.
Depending on the state you are in there are at least two (though sometimes more) different types of foster care licenses. The most well-known of course, being the adoptive license where you take a child into your care with the intention of adopting that child permanently eventually.
However, where I am at, what is really needed most are family's that will do emergency care. These are the homes that take in the children while a court decides whether the parents should be given another opportunity to make better parenting decisions or be stripped of their parenting rights. Sometimes this might mean a child arrives in the middle of the night, with fresh bruises etc. Emergency placement homes require a separate license and are not allowed to have the same children in their home for more than a set number of months (again, depending on the state one is in, this can work differently from place to place, so I am not specifying numbers here - where I am, it is less than a year).
In addition to the "new sibling" effect, I'd imagine this complex situation would have even more ramifications for our biological child. Some good, others less pleasant. Has anyone had experience with this or read any studies about it that can share some of the possible outcomes for our child while we help other children in need in a very personal way. What considerations should be made for our daughter?
