My identity crisis!

It seems an unwritten rule in my life that when ever I judge something or make an absolute in my mind--that thing happens to me. For example, my sister's son sometimes calls her by her first name. She doesn't mind at all. I thought in my head, "Oh I do not like that--my kids better always call me mom." So of course, Kes has begun calling me Riki. I think it is because Wally, the little boy I watch, calls me that as do all of the neighborhood kids and Levi (on occasion will call me that too). So what do I hear from my two year old daughter? "Riki, I'm talkin to you!" or "Riki, I''m thirsty!" I've tried several strategies for correction. I say, "I'm not Riki, I'm momma." to which she replies, "No. Riki." Aaahhh. I've tried ignoring her until she calls me mom. This usually just causes her to say my name at a much louder decimal. I think we are making progress though...she only calls me Riki about 50 percent of the time. She is so different from Bailey who when she was three was asked what her mom and dad's names where and told them "mom, and dad." I work hard to earn that special title mom (i.e. kissing booboohs, giving hugs, making meals, struggling through homework and science fair projects, doing copeous loads of laundry, playing barbies and GI Joe) and dang it they are going to call me that! I will take mom, mommy, momma, madre, mother, and even momma seta--but dang it not Riki. I feel quite strongly about this as you can see. Mother's day is coming up and all I want is for my two year old to call me mom!
