Urination training: the baby can urinate after 3 months, and practice sitting in the basin after sitting for about 3~5 minutes each time. Urine training can start from 6 months. First, train not to use diapers during the day, then wake up at night and urinate on time, and finally don't use diapers at night. In the meantime, the baby should wear pants that are easy to take off to cultivate the habit of defecation.

Training of visual and auditory abilities: For infants less than 3 months old, brightly colored and audible toys can be hung on the crib to attract children's attention. Stick to playing music for a period of time every day, and you can also sing to children. Try to choose brightly colored toys and express your approval or criticism in a gentle voice. Infants aged 6~ 12 months can cultivate their attention for a long time, guide them to observe things around them more, and let them gradually understand and be familiar with common things.

Action development: When the baby is 2 months old, he can practice lying on his back on an empty stomach, cooperate with him to turn over and look up, and expand his vision. 3-6 months, the baby likes to watch and play with small hands, grasp small toys and practice the ability to grasp. From 7 to 9 months, you can train your baby to crawl with colorful rolling toys. From 10 to 12 months, the baby begins to like to play hide-and-seek games, which can encourage the baby to learn to walk.

Language training: after the baby is born, parents can take every opportunity to talk to the baby, and the baby can learn the language by babbling. Parents can also echo the voice, talk to the baby and guide the baby to practice people, things and language. At the age of 5 or 6 months, babies will make simple motor responses to human language. 8~9 months, you can start to pay attention to cultivating conscious imitation pronunciation, such as "father" and "mother".
