A high amount of studies led by researchers determined that waking up and erratic sleeping patterns could very well affect the stimulation response of preterm infants. Preterm infants are generally unable to sleep soundly through the night. It might seem like a smaller note, but preterm infants and children with greater and more positive social interaction have been shown to sleep more soundly. A positive interaction through the womb as well could benefit infants who were born earlier than the desired term. Sleep can undergo numerous changes throughout one's life. While preterm birth cannot be avoided in some cases, getting enough sleep and a proper diet as suggested by a healthcare professional will lead to a healthier pregnancy.
