Month 1: visual ability and tactile sensitivity.

The whole skin of a newborn has a sensitive sense of touch. When he is awake, you must "talk" to him, caress and touch the baby's whole body, and provide rich visual stimulation, that is, massage the baby's brain. You can massage the baby's four fingers, palm and back of hand, and contact the action of clenching fists to make the baby's palm fully active.

The second month: the most basic big movements and sense of smell.

Practice raising your head two or three times a day to exercise the muscle strength of your baby's neck and upper arm. Give the baby a smell of soap or scented small things and see how he will react differently.

Respond to the baby's "ahhh" and "goo goo", encourage "talking" and continue to touch the baby's body.

The third month: learn to turn over and improve cognitive ability.

Turn over: let the baby lie on his side and guide him to lie on his back with toys. If the baby has difficulty in finishing, parents can help the baby turn over.

Let the baby look at himself in the mirror, and at the same time train his vision, hearing and touch to improve his cognitive ability.
