Hello Pudsy and welcome.
As a Dil until very recently, I do understand some of the difficult in- law issues you are experiencing as I had several of my own when my children were young.
I agree with David
A conversation with your husband would be beneficial.
You and your DH need to be on the same page and show a united front.
If you had posted on Mumsnet
The answer would more than likely be along the lines, it is up to your DH sort/discuss with his mother, not you.
As Dil I have one grandson.
They live a distance away.
They visit us as a family or we visit and go on trips to the park, zoo etc.
Always as a family, grandparents parents, and grandson (4 yr old) and occasion aunt uncle and cousins.
I have never asked to take our grandson out by ourselves, even though he is very loving and confident with us.
I am waiting until I feel that not only my grandson, but also his parents are comfortable with us taking him out and about.
My DD lives about 20mins drive away.
We have looked after her boys since they were babies and do after school pick ups, sleepovers etc.
Had it been the other way round and my Dil lived closer, I don't honestly know if my Dil would have been happy with such a close relationship that we share my Daughter and our grandchildren.
Good luck 
what is this behavior called does it have a name?
So it begins….. Streeting resigns
Angela Rayner cleared by HMRC. What a coincidence!
Is it rude to not finish a book club choice that was selected by someone else?
