Lullabies and the Effectiveness of White Noise in Breastfeeding

Objective: The study aims to examine the effect of lullabies and white noise on breastfeeding success in newborns.

Method: The study was conducted using a randomized controlled experimental design. The sample size, determined based on power analysis, consisted of 160 newborns, and participants were divided into four groups (female voice lullaby=40, male voice lullaby=40, white noise=40, control=40). Infants in the experimental groups were exposed to the relevant auditory stimulus during breastfeeding, while no intervention was made in the control group. Data were collected using the mother and newborn information form and the LATCH Breastfeeding Assessment Scale.

Primary outcomes

  1. LATCH Breastfeeding Assessment Scale Score

    The LATCH scale consists of five subcategories: L (Latching-on), A (Audible swallowing), T (Type of nipple), C (Comfort), and H (Help). Each subcategory is scored on a scale of 0 to 2. The total score ranges from 0 to 10, with a higher score indicating better breastfeeding success.

  2. LATCH Breastfeeding Assessment Tool Score

    Time frame: Within the first 15 minutes of breastfeeding at 24 hours postpartum

    The LATCH scale consists of 5 components (Latching-on, Audible swallowing, Type of nipple, Comfort, Help) each scored 0-2. Total score ranges from 0 to 10, with higher scores indicating better breastfeeding success.
