When does the postpartum phase begin and end?
Begins after birth and ends when mother's body returns to pre-pregnancy form.
What is sensory development?
Processes used to take in information from the environment.
How can sensory processes be affected?
By the infant's developing motor abilities.
Why is nutrition important for health and development?
