Obsessed Grandma

I have a good relationship with my mom and my baby is her first grandchild. I am happy that she loves him so much and is so interested in him, but some of the things she does are starting to bother me and I can’t tell if I’m being unreasonable.

She treated both my pregnancy and the birth of my son as a milestone for her - “becoming a grandparent” - while not really acknowledging my role or what it meant for me at all. She refers to my son as “my baby” or “Mimi’s baby” and texts me daily begging for pictures and updates or asking to see him on FaceTime. Frequently when I post photos of him on social media, she will save the photos and then make her own Facebook posts using them, rather than just sharing the existing post. Sometimes she even photos of him that I privately share with her via text. She also changed her profile picture to a picture of just my son - even I haven’t done that!

I know I’m probably being oversensitive but I just find her behavior really weird and...intrusive? I can’t really find the right words to describe it but it just rubs me the wrong way! I haven’t said anything to her about it (and probably won’t) because I don’t want to hurt her feelings. But am I crazy for feeling this way??
