Relaxation Intervention to Improve Newborn Growth and Maternal Well-being

The goal of this clinical trial is to learn if listening to a relaxation audiorecording during breastfeeding improves breastfeeding and infant outcomes and maternal well-being in a low-income country setting. The main questions it aims to answer are: * Does listening to a relaxation audiorecording during breastfeeding improve infant growth? * Does listening to a relaxation audiorecording during breastfeeding reduce maternal stress and anxiety? Researchers will compare listening to an audiorecording on a digital recording device to receiving the digital recording device without an audiorecording to see if relaxation audiorecordings work to improve breastfeeding, infant growth and maternal well-being. Participants will: * Listen to an audiorecording twice daily while breastfeeding for 12 weeks * Have study visits at 1, 2, 4 and 12 weeks for checkups and tests * Let us know what they think of the audiorecording
