I have seen literally countless threads on here complaining that GPs did this, that and the other and have offended/upset the parent.
When I was a kid, grandparents did spoil you. That was a given. It didn’t make me expect the same treatment from my parents, I understood all along that the rules were different when I was with them. I have a million fond memories of my GPs and, especially now they’re both gone, I cherish those memories.
If the grandparent of your child was a toxic parent then yes I can understand limiting or even cutting contact, but otherwise I just don’t get why people are so controlling over what GPs do when they have their grandkids over.
