While it can be uncomfortable to say "no" to family, setting up healthy and realistic boundaries is important for everyone involved. So, when a concerned dad decided to consult the moral compass of the internet otherwise known as Reddit's "Am I the As*hole?" about childcare for his grandchildren, people were quick to offer advice.
My daughter (27F) and son-in-law (30M) currently have two kids (4 and 6). They both have very intensive careers and mentioned that they were struggling with work-life balance.
They were hoping for my wife and I to help pick up the kids from school, help drive them to after school activities, and basically look over them from the 2:30-5:30pm time. To give some context, I used to do this for my three kids because I had the more flexible schedule (academia) between my wife and I. However, I also used to work every night from 10pm to 3am to make up for that time.
