Although a slightly different take on it, I thought I would tell you about my experience as the DiL being left with 3 small children.
We were all fairly close (family I mean) and I was very aware that my DSs were also cherished GSs to my departing husbands parents.
I tried to keep communication open without mentioning what was going on at home, although it turned out he'd already told his parents what he was planning to do.
I arranged for them to see the boys on a Sunday morning, dropping them at the top of the road and watching them in the door, then returning 2 hours later to collect them from the same spot.
After a few weeks, my eldest boy came out alone and said 'Granny said do you want a cup of tea?'
We haven't looked back, and, 23 years on, still have a fantastic relationship, as do my DSs and now the DGC (greatGC to them of course).
Do keep those lines of communication open Kate13. It sounds like your DiL is not looking to cause a rift between you and your GS (or DS), and I hope it works out for all of you.
So long as they all know you love them, and you can manage to not apportion blame anywhere (hard I know), hopefully you can have a long, happy, loving relationship with all 3 of them for many years to come.
