The baby is in a critical period of growth and height. When receiving hydroponic early education training, the muscles of the baby's limbs are constantly tense and relaxed, especially the alternating movements of arms and legs in water or air, which can play the role of pulling muscles and ligaments and stimulating the proliferation of epiphyseal cartilage, which is very beneficial to the growth of the spine and limbs and promotes the growth and height of the baby. It can also correct the baby's posture, improve the flexibility and coordination of the body, and make the baby look more upright and elegant.
