Pumping to Up Maternal Milk Production for Preterms

The primary outcome measure will be the volume of expressed breastmilk obtained in mL per day in the group pumping every 2 hours compared the group pumping every 3 hours

This outcome will assess the percentage of any enteral feeding that is derived from donor breast milk.

The total number of days the infant received full enteral feeds (≥120 milliliters(mL)/kilogram(kg)/day).

The number of days it takes to initially reach full enteral feeds (≥120mL/kg/day)

Infants that have enteral feeds withheld, or in other words made "nothing by mouth" (NPO) > 24 hours for feeding or abdominal issues

The total number of days the infant maintained any type of central line access.

Infants who are still receiving any volume of expressed breastmilk upon discharge will be identified and noted.

Whether or not enrolled infants are receiving all their nutrition from their mom's own expressed breastmilk upon discharge will be noted

Changes in weight measured in grams (g) from birth to 36 weeks corrected gestational age

Changes in length measured in centimeters (cm)

Change in head circumference measured in centimeters (cm)

The Bayley's cognitive component composite score will be assessed and noted.

The cognitive composite score is determined by comparing the child's performance to a normative age-matched sample defined by the assessment. They are interpreted as follows:

Mean score of 100 (Standard deviation=15) at the 50th percentile signifies mid-average functioning.

Scores below 85 (1 Standard deviation below the mean), at the 16th percentile, indicate mild impairment of being 'at risk' of developmental delay. Monitoring is recommended, along with advice to parents on techniques to enhance development or referral to a therapist based on the level of impairment.

Score below 70 (2 Standard deviation below the mean), at the second percentile, indicate moderate to severe impairment.

In general, scores falling in the lowest 10th percentile indicate developmental delay.

The Bayley's motor component composite score will be assessed and noted.

The motor composite score is determined by comparing the child's performance to a normative age-matched sample defined by the assessment. They are interpreted as follows:

Mean score of 100 (Standard deviation=15) at the 50th percentile signifies mid-average functioning.

Scores below 85 (1 Standard deviation below the mean), at the 16th percentile, indicate mild impairment of being 'at risk' of developmental delay. Monitoring is recommended, along with advice to parents on techniques to enhance development or referral to a therapist based on the level of impairment.

Score below 70 (2 Standard deviation below the mean), at the second percentile, indicate moderate to severe impairment.

In general, scores falling in the lowest 10th percentile indicate developmental delay.
