I have a 7 1/2 year old son I adopted when he was 21months old. He has been an only child and I am a single parent. I am looking at adopting again but I am unsure how I should proceed because I want my son to be accepting. I don't know if I should adopt a child younger or older than my son. I want my son notto be alienated by another child even though he wants another sibling very bad. Also would it be better to adopt another boy or a girl?
Thanksforyour help,
Wendy
