Obsessed with my belly again

I posted about this before but I just need to get it out as it’s now becoming a thing with MIL. Fist pregnancy MIL was obsessed with the baby bump. I thought it was just her way to identify with the pregnancy and first grandchild as she didn’t live near us. She wanted constant update pictures and I was getting very big all over due to swelling and water retention so I asked my husband to stop insisting we take them. She had him take candid pictures of me so she could show people and send to family. I was mad, he apologized, understood, and stopped. Now I’m pregnant again very quickly after my sons pregnancy (the siblings will be 14months) starting from 11weeks this pregnancy, when we told her I was pregnant, she’s been asking if I’m showing my husband has been saying “nope not yet” or “not that much” getting her to leave it alone. Well the other night we were painting the walls in our room and she videocalled he’s showing her the room and I’m in grubby clothes which are a little more fitted, not tight as I’m now 20 weeks, she got all excited saying she’s now showing I need picture’s because she’s getting bigger. I quickly turned away. She’s now pestering my husband in texts “make her wear a tight shirt so I can see the bump better. I need more pictures of her belly since it took her so long to get big this time.” I get she’s excited about baby like I want her to be that’s why we send ultrasound pictures which I have a ton because of 2 high risk pregnancies. I thought that would help her feel more connected to baby but apparently she just wants to see the outside bump. I’m just finding it really weird this time and am probably overthinking it all but she didn’t even want my maternity pictures from last pregnancy when all I did was show off my bump she just wants candid ugly pictures of me in tight clothes. She actually told my husband on a video call tonight just have her stand there still so we can look at the bump. Am I just a vessel for your grandchildren?!
