You have lots of great advice here already. I was a long distance Grandma, but I think I understand your query.
Keeping quiet is a must, give advice only when asked ( unless you see your Grandchild is in danger)
My goodness things have changed since my elder daughter was born nearly 40 years ago, so the changes may be a bit of a surprise.
I am now living 2 miles from my Grandchild after most of her life 400 miles away. Things have changed dramatically as my daughter and her husband are fostering two teenage children. I am about to have three grandchildren.
What a difference a day makes 😢😢
