I don't have much to add, other than I think it all depends. I grew up being raised by very young parents and I always had a bias against older parents.
But now I find myself about to place my daughter (due in August) with a mom who is 45 (that's older than my own mother is!) and her husband is 38. I don't consider them too old at all. If I did, I would have never chosen them as parents for my daughter. I hope others can give you more insight, good luck.
