Naty, you said ... The OP, however, lives down the street from DIL and their relationship _isn't good_ ...
Perhaps you didn't read these previous posts from happygran1964...
As I said I understand that she wants her family around her....
^I love my daughters in law, all three of them; not in the way I love my own daughter naturally but I do my very best to treat them all the same as each other and I lean over backwards to be supportive but to remain in the background.
I never press my opinions or offer advice and I think I am a good MIL in all honesty but yes I am upset at the moment^
For the record I actually get on really well with the other granny, we are all good friends but I don't feel comfortable talking about our children behind their backs
Maybe I'm wrong, but those statements don't sound to me like a family whose relationship 'isn't good'. On the contrary, I'd say it sounds like they've enjoyed a pretty good relationship so far. And, hopefully, I'm sure this is just a little blip which they will overcome.
