This National Pubic Radio article is based on a survey to determine how children who were adopted fare. There is not a separation under the term "domestic" adoptions for those adopted as infants, as opposed to those who were adopted by relatives--and usually older. It is estimated that 40% of all domestic (non-foster care) adoptions are by step-parents and relatives. Although there are flaws in this survey, this study does indicate what many of us already know: adoptions are successful and parents are positive and delighted in their children.
