This bottle is designed to look and feel like a mother's breast. It allows the baby to directly adapt to the breast milk bottle, reducing the mother's anxiety and the baby's uncertainty. The ergonomic design optimizes the bottle form in order to mimic the experience of breastfeeding as much as possible. Compared with similar products, this is closer to the touch of the mother's breast, making the user more comfortable holding it and allowing the baby to quickly adapt to its use.
