I don't know if you're still seeking advice. We fed our babies Kirkland formula and Enfamil Neuropro in the early days. Both of them have seed oils in their ingredient list. It is important to get his GI tract going. Calories need to go in, however that looks like. Formula is not a forever thing. It can be used in combination with pumping and breastfeeding. Whole cow's milk is not advised because it contains nutrients that are too hard on their digestive systems. It isn't suitable until they're closer to one when their tract is more mature. I'm wishing you the best for your son, DIL and grandson. Early days are hard, for grandmas too who have to support from the sidelines as the parents make their first parenting decisions.
