Where in the world did she get that from? I have always called it nursing. My daughter is almost 19 months and I always say do you want to nurse or do you want nursies. The last week or so she has decided it is called diddy. Now that I know what she means she is using it all the time. Today we were grocery shopping and she was on my back in the Mei Tai and she started crying and yelling DIDDY over and over again. People probably thought she was calling Daddy <img alt="" class="inlineimg" src="/img/vbsmilies/smilies/rolleyes.gif" style="border:0px solid;" title="rolleyes"> I flipped her to the front and nursed her (she is nursed on demand) so I guess they figured it out after that! LOL Anyways I have no idea why she is calling it diddy. What self-chosen words do your children use and do you have any idea where they got them from?
