The first is to learn to adapt to water.

Soak the head and chest first, and then slowly soak the whole body in water. Adults hold the baby's shoulders and lie on their backs in the water, with their heads above the water. Then hold the baby's chest and lie on his back in the water, leaving his head and nose out of the water. Then put the baby upright in the water, with its head on the water and moving alternately.

The second is to learn to breathe freely.

Let the baby's head be perpendicular to the water, and adults can take a bath with water in both hands. When a baby breathes through his mouth, an adult should hold the water above his head and let it drench his head.

The third is to learn to hold your breath.

The baby dips his head into the water, takes a deep breath, closes his eyes, bends his knees, puts his face into the water, holds his breath for 5- 10 seconds, and then slowly times out.

The fourth is to learn to open your eyes underwater.

After inhaling, the baby puts his head into the water, then opens his eyes and learns to see things in the water and identify the direction, which can avoid danger.

The fifth is to learn to exhale underwater.

The baby's chin is immersed in the water, blowing into the water, then taking a deep breath, then putting his face into the water, and exhaling forcefully for a long time, until all the breath is exhaled, the baby's head can be exposed to the water.

The sixth is to learn physical balance.

Let the baby walk more in the water, then the adults hold the back of the neck and let the baby slide on his back in the water. When lying on your back in the water, you can try to sink your head into the water, let your baby get together and straighten your legs or arms. Adults hold the baby's heel with one hand and your back with the other. Let the baby take a deep breath and hold it, then the adult holds the heel and pushes it forward, and the other hand is released and practiced repeatedly.
