Q. We named our newborn daughter in honor of a aunt that passed away young. At the time of the naming we were advised to add another name to the original to add a better Mazal to the child. In reality we only use the original name. Do we now have to call our daughter constantly by both names?

A. The opinion of the Poskim in regards to a Get (divorce), is that a name given at birth will remain a name, and not be considered Nishtakach (forgotten), if used occasionally even if only by one person, (see Get Mesudar p. 38a. In the name of Divrei Chaim an other Poskim). As it is customary to use the full name of birth when reciting a “Mi Sheberach”, the fact that the daughter is constantly named only one name will not interfere or hamper the double-name given at birth for Mazal Tov. Horav Shlomo Miller advices that, from time to time parents should call their child by both names.
