I am so sorry if I come across as being rude, but why is it that people have children and expect the grandparents to take care of their kids? I'm in my 30's no children and I see this all the time and it bothers me so much. If you want to have children put your children in daycare, don't put that burden on the grandparents. They have worked very hard so they can enjoy the rest of their life doing what they want to do, like see the birth of one of their grandchildren.

Read your post over again. “It just seems like all they cared about was the baby. Yes, I know it's an important occasion. But they always make a big deal about how I'm their child too, and they just desert me when I need them the most.” I read that statement and take it that you feel that your class is more important than the birth of a child in the family. Would you like to have the rolls reversed if it was your child being born? I bet not. It’s just a class, retake it.
