Hi Susan, Just to be clear -
Continuation Applications
First, and perhaps the most straight-forward continuing application, is a continuation application. Continuation applications utilize the parent application’s disclosure and claim the benefit of the parent application. In order for a continuation application to be granted the filing date of the parent application it must: (1) be filed while the parent application is pending, (2) have at least one inventor in common with the parent application, and (3) have claims that are fully supported by the parent application’s disclosure. The term “pending” in requirement (1) above is the cause of great confusion and deserves special attention. The term “pending” does not mean that the “original” application must still be pending. It simply requires that any application in the parent application and continuation application relationship is still pending.
Continuation-In-Part (CIP) Applications
The third available continuing application, known as a CIP application, contains the parent application’s disclosure PLUS additional disclosure. Claims that are supported by the parent application’s disclosure may obtain an effective filing date of the parent application, however claims that are supported by the additional disclosure may not obtain the effective filing date.

Continuation Applications lets you add claims, but no new material to your patent where as a CIP lets you add material and claims, but the new claims won’t get your original filing date.
Your patent examiner already knows about your current application, claims and prior art. Asking him about adding additional claims seems fair. Asking him about new claims for possible new material that he has not seen or checked against prior art seems more difficult to get some good advice. I think you also might have to file a document with the PTO in order to get the examiner to talk with you personally because you are currently being represented by a legal counsel. Might just depend on the examiner. Best of luck.
