I don't understand what makes you think your DIL is jealous of your GD? It's more like she is hurt, or as Farnworth suggests under valued, for herself and your son because you show more attention to your grandchild than them. They don't have children, their choice? Or are they hiding the fact that one of them is infertile? Being childless does not mean they miss having children. If that's the case, DIL may feel you are overtly emphasising their lack of children, as though they are failing in some way. I'd have a look at making sure there is a balance in the family photos.
