My son is 16 month and his name is Louis. It's a popular name and I know that but two people have commented recently that it sounds very baby and they can't think of Louis as being a grown man.
He got his name due to my DHs dad and brother have Louis as a middle name and we liked it (after checking over 3000 names on that name app) & Theodore as his middle name as my great grandfather was a Theodore.
I worked with a Louis who was really nice and never thought about it but now just wanted to hear your thoughts on this.
