DIL has one younger sister. I have known them both since their mid-teens and the younger sister doesn't seem to have had the problems with their own mother that DIL has.

THIS MIGHT JUST SAY A LOT.
This, actually, was another one of my concerns/assumptions....
We knew from previous post that DIL did not have a great relationship with her mother, and had found herself pulling away and 'cutting out' on their relationship.
Something tells me that DIL has been in the situation where she has been in a lopsided family dynamic where her younger sister is/was the 'golden child'.... She is transferring all of that hurt and psychological baggage onto YOUR situation. And, you need to understand that, and be able to handle it in an appropriate way.
From DILs (possibly skewed) perspective... She knows that when your daughter has a child, you will be there, committed, with bells on.... She is probably really struggling right now, and it seems that she doesn't feel that you even care to babysit on an occasional Saturday night. Everything she is thinking is coming thru the lense of her past experience with her own mom, and her younger sister possibly being the 'golden child'. These underlying emotions would surely be very raw and painful.
Sure, DIL may be wrong...
Sure, DIL may be crazy...
Sure DIL may be needing some help right now (in more than one way)
But, my advice remains.... Either you can get lost in your own negative feelings (hurt, anger, etc....) and you can judge her right back, and make demands and call names, etc.... etc..... (like this is really gonna help????) or you can try to look at this situation in an objective and effective way.
Whether your daughter is the golden child or not (this was never be big issue) Your son's and your DILs (based on the fact that they have been close to you almost since childhood) are still your children too.
Honestly, I really think the writing is on the wall here.
It is so obvious and very plain to see.
You need to step back, cool off, and then be the adult and step up to the plate and handle this in a mature, positive, effective manner.
