Parent-child swimming is to add parent-child elements to children on the basis of infant swimming, so that children can not only get in touch with underwater skills earlier in infancy, but also play this sport with their loved ones. The baby's early childhood is a critical period for the development of life intelligence. Grasping early education can improve the learning effect. Experts say that infancy is the fastest developing period of children's nervous system and the most critical period for developing various potentials, and it is indeed a good opportunity for education. According to the theory of sensitive period and brain development, the sensitive period of human information and ability development is concentrated in the first few years of life. This period is a unique and important development stage in human life, an opportunity window for children's development and the best opportunity for babies to gain wisdom. The core of early education is to provide an educational and nutritious environment to "activate" children's brain development and personality growth, thus laying a solid foundation for their future development. I hope my answer is helpful to you, and I wish the baby a healthy growth.
