Dear Abby: Grandmother torn between helping family and personal time

Dear Abby: My son and his wife have two children. The youngest is a baby and is my first grandchild fathered by my son. I have a special relationship with the baby and have been caring for him since he was 2 1/2 months old, Monday through Friday from 8 to 5. The idea was that I would watch him until he was a year and a little bit, and then he would go to day care. Day care is very expensive, and I’ve recently been told they may not be able to afford it at this point.
