15-month-old baby's development index: small hands are more flexible.

Baby's small hands are flexible and can fold two building blocks. A baby with strong hands-on ability may pile three or four blocks together. The baby will take out the toys in the bucket and put them back in the bucket. I can eat with my own spoon, pick up a small rice bowl with both hands, and drink milk and water with a bottle in one hand, which is very chic.

Height: The influence of heredity on baby's height is more and more obvious.

Head circumference: since the beginning of infancy, the change of head circumference has been very small, so there is no need to measure it again.

sports

Babies who have just learned to walk always open their arms and can't hang down at their sides naturally. This is because babies must use their own arms to adjust their balance, just like the two wings of an airplane and the two wings of a butterfly. When the baby is steady and balanced, the baby's arm will be put down.

A walking baby, at this age, will hold the railing or other objects, lift a little foot and kick the ball away. Mom and dad should not underestimate the baby's "one-legged lift", which is as difficult as the national football team.

The baby's physical exercise ability is gradually enhanced, and he will climb with small stools, tables, sofas and other objects. The baby may climb 6 ~ 10 steps alone. If the mother holds the baby's hand, the baby may stand up for several steps.

Physical skill development

Baby's small hands are flexible and can fold two building blocks. A baby with strong hands-on ability may pile three or four blocks together. The baby will take out the toys in the bucket and put them back in the bucket. I can eat with my own spoon, pick up a small rice bowl with both hands, and drink milk and water with a bottle in one hand, which is very chic. Mom may be surprised to find that the baby can still hold a straw as thick as a string with his index finger and thumb.

Most babies of this age can hold pens. Letting the baby doodle with a pen is a good way to train the flexibility and accuracy of the hand.

The baby can drink the water in the cup, but he can drink most of the water into his stomach. It is normal for water to splash on clothes, neck and ground. Not only don't criticize, but also praise the baby.

The baby will insert his finger into the bottle mouth. This ability makes the baby very happy, as if he were possessed. As long as he sees a hole or an eye, the baby will insert his finger. This is one of the ways for babies to exercise their hands carefully, and mothers can buy such toys for their babies. Don't use baby bottles and toys with small holes, lest the baby put his finger into the bottle mouth and can't take it out.

Language development

A baby who speaks early may say one or two or three sentences. Most babies can consciously call their parents, even grandpa, grandma, grandpa, uncle and aunt.

Such a big baby began to like talking to relatives around him, expressing rich meanings with few words. More than half of people can express their wishes by using 8 ~ 19 words or similar words, or actions representing the meanings of these words. More than half can understand the meaning of 100 ~ 150 representative words, and more than half can understand the meaning of more than 20 phrases. Although the baby's vocabulary is limited, he can express his thoughts and demands through various non-verbal means and borrowing methods. In the eyes of the baby, a sentence is exactly the same as a voice, a gesture, a posture and an expression, and it is only a small part of the language.

Babies don't completely repeat their parents' words, which will reintegrate the language they hear, so they often say things that their parents never said. This shows that the baby has been able to think independently and express his views and wishes.

Cognitive state

When reading with children, you will find that children have the ability to understand and answer with sounds and expressions. Let the children turn over the books by themselves when reading. Children already know what is good and what is bad, and remember stories.

Therefore, when you are free every day, you can share these wonderful times by reading to your baby before going to bed. At the same time, reading will stimulate the baby's curiosity, imagination and desire to speak.

Social skills

Before the age of three, the baby will not be a good game partner. When I am with my children, I always play with myself and lack communication with each other. This does not mean that they are not interested in each other, but because at this age, the baby has not learned to share and cooperate. Playing and getting along with other children is still an important way for babies to socialize.

Emotional development

This one-month-old baby, on the one hand, has independent will and adventurous spirit, on the other hand, it is prone to fear and loneliness. Children's understanding is still quite limited. When something happened that he couldn't understand and explain; When he doesn't know whether what happened in front of him poses a threat to him; When he sees something he has never seen before, and it is such a strange thing, the child will naturally feel a sense of fear. Babies not only have limited understanding ability, but also have limited knowledge of the unknown world, so their fear is not as strong as that of young children.

Parents should try to avoid the baby from having too much fear. If parents are unrealistic and let the baby accept what he can't understand, it will not only make the baby progress, but also shrink back because of excessive fear.
