Ticked off about my baby shower

My mom sent the invitations out last week the baby shower is next weekend. No one can come because of the short notice. I told her to send them out at least a month before. Not to mention she is just going to rush through the party because they double booked themselves with moving into their new house. They knew about the baby shower longer then the new house. They made sure everything was perfect for my brothers wife's baby shower but their only daughters is thrown together.
