Investigate Effects of a2 Milk on Breastmilk Composition and Subsequent Infant Gut Health, Crying and Sleep Patterns in Healthy, Full-term Infants
Study Details
Study Description
Brief Summary
The goal of this interventional study is to investigate effects of a2 Full Cream Milk on Breastmilk composition and subsequent Infant gut health, crying frequency and sleep patterns in Healthy Full-term Infants.
50 mothers and thier infants will be enrolled into 2 study sites, mother and her child as one subject will be randomized to 2 groups for assigned interventions, a2 Full Cream Milk and conventional Milk (Weidendorf). The study will continue for 14 days, and 3 site visits will be made duing the study period. All data specified in the protocol will be captured and recorded into CTMS for analysis.
Researchers will compare the two groups of participants to see if a2 Full Cream Milk has significantly better breastmilk composition and improve infant's gut health, crying frequency and sleep patterns.
