Everyone pretty much covered it. They shouldn’t be neglected and light work will be more than fine. I’m sure it boils down to genetics. I had a friend who was really skinny but had huge (perfectly sculpted) calves that a bodybuilder would die for. His father was built exactly the same way. In my family it’s back and shoulders in another friend’s family it biceps and forearms.

The ‘overdeveloped’ view could be how your client views his (or her) calves.
As Harris and Christine said it could be genetics (unfortunately that is not in your control).
There’s no need to place heavy emphasis on calves (other areas can receive more attention) but you can use Karin’s idea about the calves.
One area is important: if her calves receive a lot of attention what about the tibialis anterior (is the muscle that opposes the calves ‘overdeveloped’)?
Genetics may play a role in the size of your client’s calves and there won’t be much you can do about that. However, you can still incorporate strength exercises without fear of “bulking up”.
A balanced strength training routine should still be part of your client’s program for many other health benefits–and your client may find that focusing on developing other areas builds confidence.
There is really nothing you or she can do about this. Genetics cannot be changed. You can have her do all types of exercises without focusing on the calves alone (for ex. no calf raises). Walking alone exercises the calf muscle, so even if you advise her not to do any weight training for her calves, they will still get worked out indirectly.
