should I not be upset 😕

My mother-in-law came to visit yesterday my BF and his mother and son went out while I stood home with our newborn baby . That's not what upset me though what upset me was that just right now there showing me all these professional pictures they got done all together and our little girl wasn't in them . I kinda felt as if she was rubbing them in my face . My BF son is her first and favorite grandchild . I'm usually not a person to care about this stuff but it really did upset me that it was like a family picture without the baby . Am I wrong to feel upset ?
