...that's totally the parents' call...there are really two issues, 1. that some parents do use the baby terms, and we all agree ( so far !) that is wrong and 2. Are "correct" or slang terms in a show appropriate for certain ages. I remember my mother thought the T & A song from a Chorus Line was shocking when I went on a school field trip to see it waaaay back. I don't know how old your daughter is, but it is certainly up to you to decide what shows she sees.
