There are advantages and disadvantages in both the common and
unusual names.
For example, a common name like Michael is both easy to pronounce
and remember but the name is common, so there is a high possibility
that there might be quite a few other Michaels in your childs class or
workplace.
An unusual name may make your child stand out from the restbut
the question is would she or he want to stand out? If your child is shy
and does not like attention, this may be a problem. However, if your
child likes the spotlight, then it may be a good thing.
