Well, I'm a little sideways on your question, but you might find the input at least a little helpful. I am an adoptee and an adoptive parent. My parents were always completely supportive of me connecting with my birthparents. I had never had any desire to, so I just haven't. My adoptive brother did, though, with my parents' assistance. It was a disaster! Years later we're still trying to help him pick up the pieces. Mother would no doubt face me searching with much trepidation now because of what happened to my brother. As parents, you never want your children to suffer. I think part of the reluctance some parents have about their children connecting with the birthparents is that they can't stand to see their children hurt.
My baby is only 4 months old right now. We have a closed adoption. (We believe that a closed adoption is much better for the children, although that comment should get me some negative feedback.) Anyway, we have a letter her bmother wrote to her along with a picture of the bmother and DD's older half sister. We fully intend to share that with her when she's old enough to understand. The letter is beautiful and explains the relinquishment, and DD will no doubt be asking about people who "look like her". That's natural.
So, I wouldn't search myself, but I am not necessarily opposed to DD looking when she gets older.
Not sure that makes a lot of sense, but there you have it.
