MIL rant!

I'm probably being an over-reactant 38 week pregnant woman. However, my mother in law called me to inform me that when she came down to see the baby - her, my husband, and our baby were going to have family (generation) photos done. 
Am I being ridiculous for thinking this is a little rude? I guess I feel like I should be able to have some entire family photos. Her son didn't do this himself! 
Again, I'm probably being horrible. It's just been a complicated pregnancy and I feel as though everyone's excitement and eagerness is going to overshadow personal bonding time with the baby.
