Forcing grandparents visits

[Seasunandsandles]

Im staying with my mil for a week over Xmas
We generally get on well but she can be controlling and over step boundaries sometimes. Her latest obsession is constantly asking my son (he's 9) to visit her mil who lives round the corner. Now my son adores his great granny and enjoys visiting her . He goes off his own accord once or twice per day during our visits. We usually visit over a weekend or stay a week.

One a day that he doesn't visit my mil will ask him over and over again, go up and your granny, it's really repetitive and annoying. Drives me mad to be honest.
Im on the verge of saying something, as its like bullying . My son says no I don't want to but she persists until he gives in. Or I step in

can your DH have a word?

That is pretty annoying,
my mil is like that with my boy and food, constantly offering food, asking if he wants something, asking if he has eaten and what we will give him etc etc.. since my boy can now talk i just teach him to lay his own boundaries down well, like say ‘no thanks’ or ‘my belly is full’ and I just ignore her 🤷‍♀️
so if your boy expresses to you he doesn’t actually want to go and has done his polite visit for the day, just encourage him to politely continue setting boundaries.
