My Baby boys name is Sir Arthur Lee Merlino, but I call him Artie, but he won't respond unless you say it with an eastcoast accent (my husbands from Boston, Go Red Sox!)
so it sounds like "ottieeee". I also call him; Baby baby, little man and hoy (a filipino slang term) when I want to get his attention quickly! He responds to all of them. I think it's just my voice and tone I use, depending on my mood. He is with me all the time. except for 2.5 hours a day Monday thru Friday other than that we are inseperable.
