The trauma still happened to the kid, whether he remembers it or not. If there are clinical studies that show psychological trauma at age 2 or 3 does not matter because of memory, I'll gladly be wrong, but I don't want to inflict distress in my kids. Not to mention seeing your kids being miserable crushes your spirits as well.
