The goal of this clinical trial is to learn about the effect of breast-pumping frequency on breast milk supply/ volume in mothers of preterm infants. The main question it aims to answer is: \- What effect does pumping frequency have on breast milk supply. Researchers will compare breastmilk supply of mothers who pump every 2 hours to the supply of those who pump every 3 hours to see if there is a difference in the amount of breastmilk they produce. Participants will be assigned to either pump every 2 hours or every 3 hours and record how many milliliters of breastmilk they produce daily for the first 28 days of their baby's life.

RECRUITINGVolume of expressed breastmilk
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
Time frame: From enrollment to 28 days of life
The percentage of donor breast milk feedings
This outcome will assess the percentage of any enteral feeding that is derived from donor breast milk.
Time frame: From enrollment to 28 days of life
The number of days alive on full feedings
The total number of days the infant received full enteral feeds (≥120 milliliters(mL)/kilogram(kg)/day).
Time frame: From enrollment to 28 days of life
The time to full feedings
The number of days it takes to initially reach full enteral feeds (≥120mL/kg/day)
Time frame: From enrollment to 28 days of life
The number of infants with clinical evidence of feeding intolerance
Infants that have enteral feeds withheld, or in other words made "nothing by mouth" (NPO) \> 24 hours for feeding or abdominal issues
Time frame: From enrollment to first 28 days after birth
Number of central line days
The total number of days the infant maintained any type of central line access.
Time frame: In the first 28 days of life
The number of infants receiving any volume of breastmilk at time of discharge
Infants who are still receiving any volume of expressed breastmilk upon discharge will be identified and noted.
Time frame: From enrollment to hospital discharge
The number of infants exclusively feeding breastmilk at discharge
Whether or not enrolled infants are receiving all their nutrition from their mom's own expressed breastmilk upon discharge will be noted
Time frame: From enrollment to hospital discharge

The Bayley Scales of Infant and Toddler Development (BSID)
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.
Time frame: from 18-26 months of age
The Bayley Scales of Infant and Toddler Development (BSID)
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.
