Is it possible to avoid others calling your young child by a nickname/shortening? I know that nicknames can't be avoided if the child reaches a certain age and prefers one, but I'm only referring to when the child is a baby and toddler. We like the name Cassandra but not the nicknames Cassie and Sandra. There are also other names that we liked but won't consider because the common nicknames are awful. I really don't see the point of nicknames in general. They often are not as nice as the full name. (I know that what I'm referring to are technically called diminutives, but it's easier to say nicknames as everyone will know what I mean.)
