What are the developmental standards for a four-month-old baby?

When the baby is four months old, parents can start training the baby. For example, you can use a rattle to knock next to the baby, and the baby will look for the direction of the sound. The baby at this time will have a quick response to sound and light. You can even play simple hide-and-seek games with the baby at this time. This can promote the baby's brain development. The following introduces the development standards for a four-month-old baby.

Developmental standards for babies aged four months:

When the baby is four months old, all aspects of his body and abilities are constantly developing and gradually moving towards a better level. At this time, the baby himself is also constantly exploring and understanding this world full of unknown factors. So what are the development indicators of a four-month-old baby?

1. Indicators of physical activity

With mom and dad supporting the baby's hip joints, the baby can sit up by himself and try to turn over by himself. The baby can lift his whole body with his hands and can sit for about ten to fifteen minutes. The baby can lift his head and straighten his back. The baby can also stretch his neck and reach his feet with his hands and try to bend over by himself. The baby can lie on his stomach and roll over to lie on his side.

2. Language proficiency indicators

A four-month-old baby can detect his own sound-making organs. He likes to try to have conversations with mom and dad, talk to himself, entertain himself, and learn to babble. At this time, the baby can shout, laugh loudly, make crying sounds, and try to imitate the tone of adults.

3. Tactile indicators

The brain nerve development of a four-month-old baby is gradually improving. At this time, the baby's conditioned reflex will gradually disappear, and the baby will actively reach out to grab the things and toys that interest him. At this time, mom and dad can play with the baby more, use some toys to amuse the baby, and he can actively reach out and grab them.

A 4-month-old baby's head circumference and chest circumference are roughly equal. The baby is more than 10 cm taller than when he was born, and weighs about twice as much as when he was just born. When lying on his stomach, the baby's upper body can be fully lifted; the legs can be raised to kick off clothes and quilts; the vision becomes very flexible; he begins to babble and responds to adults' teasing with voice; and complementary foods can be added. Overview of intellectual development at 4 months: 1. Body movement and control: When the baby is lying on his stomach, he can use his hands (note that it is not his elbows) to support his head and chest. 2. Exploration and manipulation: When the baby sees a toy that attracts him, he can reach out and grab it. 3. Language: When the baby hears someone calling his name, he can react quickly. 4. Social adaptation: When the baby sees someone who often holds him, he will show that he wants to be held. You can play hide-and-seek with the baby with a snare drum: Beat the snare drum in front of the baby to tease the baby to look at it, then cover the snare drum with a towel to see if the baby will lift the towel and actively look for the source of the sound (snare drum). If the baby does not make searching movements, the parent can put his hand into the towel, hit the snare drum again, and guide the baby to lift the towel and look for the snare drum that makes the sound. Game purpose: To develop baby's hearing, stimulate baby's interest in exploring the environment and promote brain development.
