I love
Max but only as a nickname for
Maxwell. It seems too nicknamey and insubstantial to me to stand on its own, and I don't like
Maximilian too much. I love
Maxwell, nn
Max. If I had ever had a second son, I would have seriously considered this name.
My sister commented once that
Max is trendy and popular, but I have never met one, even a child. There were no little boys named
Max in my children's school classes, so it never seemed too trendy to me.
