Before we did our last IVF we were in the process of waiting for PA to reinstate their foster to adopt program. I remember there were a ton of classes that we were getting signed up to do.
Where I work we have foster children come in, and some that are taken into foster care.
It takes patience, and understanding that the are coming from a place where there was (in many times) no structure and what you would call normal isnt what they consider normal. Its going to take some time to relearn how to act right.
In pa we could have chosen the age of the foster child/children from newborn on up.
that may be something to consider. Also there is a window where the birth parents can get them back, just something to consider.
I wish you the best, we really considered that way into adoption but our last frozen cycle ivf worked.
