Concerned about special needs of int'l adopted kids

Hi everyone. My husband and I (I'm 50, he's 40, no children) are considering adopting from Russia. I've been talking with adoptive moms, and am feeling very sobered by the experience, particularly with those who have dealt with RAD issues (I know everyone has bonding issues to some extent) - but to be treated on some level, 5 years out, as "just another caregiver.?" I'm not sure I could deal with that. Looking for the strength to move ahead...we've identified homestudy and placement agencies, just need a little bit of trust and faith that we won't regret this decision. We're looking for a young sibling group (girl/boy), as young as possible, which could be 2-3 yrs. plus, because of my age. Any advice/inspiration greatly appreciated! Thanks so much, Sandra
