Jealous of MIL holding my baby

My MIL is usually nice to me which is why I don’t understand why I feel like this. She has said things in the past when I was pregnant that made me feel certain ways towards her, she was upset my husband would be moving in with me and upset he’s always there for me when I’m sick (I had horrible morning sickness throughout my pregnancy) , and getting me food,etc.. his parents said I wasn’t compromising with husband because he moving into MY house and MIL said she was scared she won’t get to see my husband if he lived in with me. she was upset about those things and saying she doesn’t get enough time with him. when we visit she usually doesn’t say one word to me. She will talk to my husband but not to me. I am a bit shy so I don’t hold it against her too much bc I am bad at starting conversations. We visit about once or twice every week or 2 for a few hours.. but the entire time she holds my 2 month old since she was a newborn the whole time we visit besides when I BF or she needs changed. It bothers me because she almost acts like her mom and I’m nervous she will bond better with MIL. I know she won’t but it’s in my head. As soon as we get there she makes my husband put the car seat next to her and she takes my baby. We told her one time that we were going to be leaving in 15 minutes and she held my crying baby for the whole 15 mins and was whispering to her “you aren’t going to let me get these last 15 mins are you?” I feel horrible feeling this way and I love that she loves my baby. I know it’s wrong to feel this way but I can’t help it. Is there anything I can do to help?
