The journey of human development begins long before birth, with the prenatal stage, commonly referred to as development in utero, spanning from conception to birth. A lot more than just physical development happens during the 40 weeks a baby spends growing in his or her mother’s womb.
The following video outlines the development stages of an unborn baby in relation to their gestation:

Understanding development in utero allows us to recognise the significance of early interventions, maternal health and supportive environments.
