We manage the blessing of procreation but it is still God who blesses. It is the same as when we establish a family budget. Psalm 119 reflects God's view that life exists in the womb. Fetal scopes pick up the unborn child's heart beat. Ultrasound and fiber optic technology have allowed us to view into the womb and see that child growing and alive.
Surgery can be and has been performed on the child in the womb.
In a very practical way an unborn child is treated as a second patient under a doctor's care. We should first realize that sometimes funerals are held for children lost in a miscarriage. Remember, funerals are held for the benefit of the survivors. Nevertheless, a funeral for a child lost through miscarriage is more the exception than the rule. Practical reasons for that are that miscarriages often take place so early in a pregnancy that it is either not known a miscarriage has taken place or little is left to bury.
