No you should not be jealous or upset! this is her mother and father, she has every right to kiss them goodbye.
as for the seeing each other naked thing, her mother has been seeing her daughter naked since she was a little girl when she was bathing her as a child. honestly, its a mother/ daughter relationship!
How would you feel if your girlfriend said she didnt feel special because your mother changed your nappies as a child?
But, if it does make you feel uncomfortable you should talk to her about it and things. the problem will never sort itself out if you dont face it head on. you should talk to her about it, and see what she thinks about it.
Good Luck.
