Prenatal environmental influences (1978)

"File: Human Relations, 5/78/8M""Many things can cause death or deformity to the unborn baby. Examples are poor nutrition, disease, drugs, smoking, and radiation. The damage depends on the nature, amount, and time they are introduced into the developing infant. Timing is the critical factor in determining if an environmental influence will produce any bad effects. If an organism is forming when a destructive agent is introduced, it may never develop fully."--First paragraph.Phyllis A. Pirner (Child and Family Development Specialist), Ann A.
