Kids nicknames

My husband calls my daughter "똥똥 Junior" and I call her "Baby" because that's what she is. "똥똥 Ddong Ddong" in Korean translates to "Poopie" and somehow it's a "cute" nickname to call in Korea. I don't really agree though. I mostly call my baby by her name and so does my father. I believe it's important for her to recognise her own name rather than a nickname.
