I’ve wondered about such studies, too, Aimee. So far, we haven’t found anything that might be related to me taking the dex while pregnant with my daughter whose is almost 8, but who knows what life will bring her?? And it would be hard to tell if was from treatment in utero, or from the steriods that she takes every day. It’s another scary part of being a parent - you take the information you have and try to make the decision that you believe is the right one. My grandma says that all you can do is, "Your best ... and PRAY like crazy!" Let us know, please, if you ever hear of such studies - I’d be willing if it was nothing too invasive. Blessings
