Order terminating mother's parental rights to her children under Welfare and Institutions Code section 366.26 is affirmed over claims of error that the juvenile court's finding that the children were adoptable was not supported by substantial evidence because: 1) there was no evidence of any other approved homes that were willing to take the children or children with their characteristics; 2) the children had severe behavioral problems; and 3) the children were part of a large sibling set.
