What is your thoughts on adoption?

My nephew is adopted and it is a wonderful thing. He does know he is adopted and he gets to celebrate his birthday and his adoption day too. He loves it! He was a baby when he was adopted and now he just had his second child. I think that his life is so much better then it may have been if he hadn't been. For him having the birth parents involved would have been a bad thing because they were in trouble in many areas. I remember once my sister was contacted to warn her the father was looking for him. I say warned because he was not a nice man. My sister was very nervous but he never showed up. I guess seeing my nephew's situation I would not want the birth parents involved. I do know of others where the birth mother met the family and gave them the baby and they are working out well. I am just not really sure how I would feel about having the birth parents involved if I was adopting.
