I realize it is kind of awkward to ask this question on a MacRumors forum, but this forum is full of normal people who belong to normal society, and so I feel like I could get some useful reflection on this situation here. My wife and I have a 7 month old baby. My wife really hates my mother. My mother does have issues, and many of the tell-tale signs of a narcissist. My wife is okay with my mom coming to visit us sometimes, but wants to limit the frequency and duration of the visits, because she hates my mom. My mom is really excited about the baby, it's her first grandchild. I want to let her come visit on a fairly regular basis. Given how my wife feels about my mom, what is reasonable for me to suggest in terms of how often we should have my mom over for a visit?
