Legal Free Adoptions

I saw my daughter off Adoption Exchange in Feb 2009, she moved in in December 2009. Adopted in June 2010. She came into my foster home legally free, things went smooth, and no concerns. She was 8 when she got placed. No medical issues. Then last October 2011 same caseworker calls me asked if I would be interested in a sibling group of 2 on her caseload. She said that they are 11 months and 2 years old- both boys, and healthy. Also legally free. They moved in, December 2011 and last June 2012 they were adopted. Therefore they both went amazingly smooth.
