My MIL has called my husband twice and said I am disrespectful towards her. Her examples of how I am disrespectful are: The day after my daughter was born, she was admitted into the NICU with heart and lung complications. I was very emotional (I thought any mom would be in that circumstance). I had no idea when my baby was coming home. It was time to breastfeed my daughter so I went downstairs to the NICU with my mom pushing me in the wheelchair. Only two people are allowed in the baby’s room. My MIL was in there when we got back there. She knew she had to leave because it was time to feed Kiya (my baby). She told me hey when I got back there and I said “Hey, how are you?” She replied and continued to talk about how Kiya had a lot of hair and how cute she was. I smiled and said “Yes ma’am. Thank you.” She then said she was going to step outside, so I could feed Kiya. I said “Yes ma’am.” Three weeks later, she called my husband and she said I was disrespectful that day because I didn’t have a detailed conversations with her. Keep in mind, I was in pain (emotionally, physically and mentally). I am also VERY shy and she knows this. She also called my husband while I was in the hospital and said “I bet Kayla is going to act up when she leaves today.” Seriously?!!! I had no idea when my daughter would come home with me or if she ever would. I felt like she was disrespectful towards me by saying that to my husband. QUESTION: Was I disrespecting her by not having a detailed conversation that day in the NICU? & Was she in the wrong for what she told my husband?

Phone call 2: My MIL told my husband that she thinks I’m disrespectful because I don’t have detailed conversations with her every time we go see her. Keep in my mind, I always use my manners (yes ma’am & no ma’am), I always smile, I am very shy, and she is very intimidating. I don’t like the way she treats my husband. I have very good reasons, but to keep this post as short as possible, I won’t go into detail. Whenever she asks me questions that require more than yes ma’am or no ma’am, I always respond to the best of my abilities. For example, we talked for 30 minutes one day about Christmas gifts. QUESTION: By not always having very detailed conversations with my MIL, am I being disrespectful?

Thank you to everyone who took the time to read this and respond!!❤️❤️❤️
