I wish we had something else to call MIL.
This is why I really had a hard time calling my MIL by her first name, even though this is what she told me to call her. I just felt (and still feel) very disrespectful when I do this. My DH and I have almost been married 10 years. I was very relieved once we had a child so I could just call her, "Grammie"! That feels better to me!
