ahh brings back so many frustrating memories! I have a part time boy (he is now five years old) but I have been taking care of him since he was two. He went through this really annoying stage where he would call my name unconsciously, over and over again while he was playing. This would go on ALL DAY! He would call me, but when i answered him or responded to my name, he would look at me blankly because he didn't want anything. Finally, to save my sanity, I had to learn to ignore him calling my name. I learned to tell the difference between him chanting my name like some sort of mantra, and when he really wanted something. Thank god he outgrew it when he turned four!
