A grandparent’s duty?

A friend of mine, let’s call her Mary, has been arguing with her parents lately.

She’s got 2 small children and is struggling with looking after them and working part-time. She’s lucky enough to have a loving husband and parents who live nearby. Her mum and dad look after the kids for her about once a week – but Mary’s always moaning that they should do more.

Don’t get me wrong, I understand how tough being a parent can be, but I really don’t think baby sitting should be an obligation of the grandparents.

Mary’s mum and dad are now retired and enjoying themselves. They don’t want to give up their weekends all the time, and I can’t say I blame them!

I want to tell Mary she’s being unreasonable, but she’s so sensitive about it. What should I do?!?
