Features: BPA and BPS-free polypropylene were produced. Temporarily removes the flat or inward nipples. One-handed, fast and easy to use. There is a small box for hygiene and easy transport. Explanation: The first step of a successful breastfeeding is that the baby can grasp the mother's breast properly. Latch Assist TM The Breast Extractor is a simple and practical tool that temporarily pulls straight or inward nipples out. Usage: Before use, rinse and rinse the Latch Assist TM Bump Extractor in hot soapy water and allow to dry at room temperature. After bringing the baby to breastfeeding position, gently squeeze the purple ampoule and place the chest applicator in your chest tip to cover the breast tip. Press the chest applicator lightly against your skin to avoid airflow. Slowly release the light bulb and wait for a while so that the desired pressure will be supplied. Repeat this move until you can easily grasp your chest tip and your baby's chest. Throw away the milk that accumulates in the bulb. After use, rinse the Latch Assist TM Bacterium Remover, rinse it out and let it dry at room temperature.
