first 2 weeks Conception, implantation, formation of placenta Fewer than half survive beyond this stage

Embryonic stage

2 weeks - 2 months Formation of vital organs and systems

Fetal stage

2 months - birth Bodily growth continues, movement capability begins, brain cells multiply Age of viability - after 25 weeks (can exist outside of womb)

Maternal nutrition

Malnutrition linked to increased risk of birth complications, neurological problems, and psychopathology
