Undergoing Divorce, Our Child That We Currently Share 50/50 Custody Of Is Calling My Ex’s New “friend” Their New Mommy. Do I Need To Inform My Lawyer Of This?

Filed for divorce near the end of Summer, it is still ongoing. I believe my ex has been with this new “friend” for a while, but has only just recently been bringing this friend around our child. My lawyer advised me early on not to expose any potential “friends” around our child (I would never even dream of doing that anyways). I wasn’t really comfortable with the idea of my ex bringing someone around our child so soon, but of course I can’t dictate his life during his time with them. But now that they are referring to this friend as “new mommy”, I’m wondering if this is something I need to inform my lawyer about bc it goes against the advice I was given.
