Will you adopt?

So as the trial date for severance gets closer and grandma in Massachusetts ended up not being able to take the kids, they have asked us if we would be willing to adopt R. Woah what a big decision but not a hard decision. We would love to have him as a permanent part of our family. Forever a family of FIVE. Crazy to think of. His oldest sister actually recently was able to go and live with the grandmother on the other side of the family, dad's mom. She is not able to take all three kids because she is getting older, she is single, and financially unable to care for all of them. So they came to us and asked if we would take R and they asked R's little sisters foster mom if she would adapt. CPS does not like to separate the siblings but is going to present to the judge that they all three have forever homes and plan on letting the siblings keep in touch. Its going to hard to wait and see how this will play out but going to keep praying that Gods will is the result and R is exactly where he is suppose to be.
