Sometimes people use names for their pets that they love enough to use for a child, but they are not planning on having any more or any children. That's why I once had a dog named
Miranda and my sister once had a dog named
Sean.
However, if some accident had occurred to either of us, or if our plans had changed, I may have named a daughter
Miranda and my sister may have named a son
Sean. In this case, it would be because we wouldn't have wanted to eliminate a name we loved because we at one time thought we wouldn't have more children. It wouldn't have been naming the child after the pet.
