I’m really glad my grandparents were a part of my life growing up. My Nanna and Pa lived closer so I saw them a lot more. They helped out a lot. My Grandma and Grandad were over 12 hrs drive away so they had us for some holidays, phone calls, etc.
I have many wonderful memories. I learnt about what life was like in the olden days when they were young. I learnt lots of other valuable life skills too.
I remember complaining to my nanna about all my chores I had to do, how it was unfair because my friends at school didn’t have to do so many. Then I asked her if she had to do chores. She told me how she had to pluck the feathers out of the chickens after her dad had cut their heads off. They didn’t have supermarket chicken back then. My mouth fell open and I realised how lucky I was to not have to do that chore. 
But they were from a completely different generation from grandparents today. They lived through the Great Depression and World war. They placed value on everyone pitching in and helping out, the it takes a village to raise the children.
My parents generation went through a massive cultural shift and part of that was the finding yourself movement. So, while there are plenty of parents from this generation who will help with the grandchildren I think many do not. Instead of viewing it as family pitching in and helping each other or it takes a village to raise children, it is viewed as unpaid baby sitting.
However, if grandparents are of an age with it being too much to have the grandchildren on their own, then family members should understand and respect that.
I hope that I’m still around and able to be a part of any future grandchildren’s lives one day. Just like my grandparents were for me.
