I do not believe that it is right to offer "cute words" to children. Childhood is the time when most language skills develop, and I believe it causes a great disservice to offer incorrect words to children. Children have enough to do to learn the names of everything in their environment once, and it is a waste to make them relearn certain terms just because adults thought it was cute to teach them the wrong name to begin with.David Quinn wrote:"Panties" resembles all those cute words you normally offer in conversation with young children - e.g. "din-dins" (for dinner), "sweetie", "walkies" (for taking a walk), etc.
One might argue that this is harmless, but there can be lasting effects, especially amongst females who are expected to retain a certain child-like quality. Many of the cute words go away as the child matures, and fathers are especially good at teaching their sons that men say "walk" not "walkie." Females might not be reinstructed, and before you know it, you have a woman saying "bouncy ball" rather than "rubber ball" or someone like my mother who said "eggie" rather than "egg" her whole life (which I found mortifying).
In the infant stage, a child does not have the muscular development to form words properly, but a child already has a good understanding of language long before their first word. This has been proven by psychologists, and I have one memory from before I was old enough to speak that includes the words my mother said to me. Just because a child can not physically form the words correctly does not mean the parents should revert to saying "ba-ba" themselves (rather than blanket, bottle, pacifier, or whatever that means in a certain house). If a parent knows that "ba-ba" is as close as a child can utter to a particular word, and they know what that word is, that is good - but encouragement of proper names should continue to assist in language development, and help prevent "cute" words from slipping into an adult's vocabulary.
