intrusive mother in law or over reacting?

Lizet

So I've been living with my boyfriend for a little over a year and a half. we had our baby 4 days ago. His mom just as my mom has been over every day yo visit the baby. But today when she came she had her daughter who takes semi professional pictures come to take newborn pictures of the baby. I can't help to feel like that ot wasn't her place. He's my son and that's something I wanted to do for him. I wanted to take the time to find a outfit, and find different posses. I understand it's her first grandbaby but I also feel like it was intrusive. I don't have a great relationship with her but I do feel like she could have asked. It's something I would have been open to doing together. AM I BEING IVER SENSITIVE OR OVER REACTING? ARE MY FEELING JUSTIFIED? I tried talking with my boyfriend but he feels like I'm attacking his mom. And that I'm overreacting. HELP ME
