Prayer....
Update: My DIL, the mother, received a D&C last night to extract the wee remains of the babies, which were just in the first trimester. When I spoke with my son on the phone he seemed at peace. Since theirs is a Catholic hospital, the remains were treated with utmost respect, and there was a religious sister to pray with them.
I know that my little grandchildren are with the Lord, and I pray that they are being cradled by their great-grandparents and their uncle.
God bless all of you for your prayers and your words of wisdom and comfort.
