How to evaluate the development of babies under the age of three? Let’s look at these reference indicators.

Each baby has its own unique growth rhythm. Some babies can walk at the age of 6 months, while others have to wait until about 15 months before taking the first step. Some babies can answer questions as soon as they are 15 months old, while others have just begun to speak at this time.

The individual difference of the baby’s development is very big, so it is not easy to judge whether the baby’s growth retardation must be treated. The following table roughly sorts out the key signs in the development process of most babies, and parents can check the table to see if the baby has reached the corresponding age index.

Large muscle movements: large limb movements and the strength of large muscle groups; Fine movements: fine movements of hands and coordinated movements of hands and eyes.

Language: including the development of speech and body language; Social interaction: baby’s interaction skills with others.

Need to remind: The list in the table is only the development level that most normal babies should reach. If the baby has one item that does not meet the standard, it does not mean that he is stunted. If the baby is stunted for more than 2-3 months, he should ask a pediatrician to conduct a comprehensive examination for the child in time and make an evaluation.

If the child has the following conditions, he should also tell the doctor when seeing a doctor so as to find abnormalities as early as possible.

Big action:

    I still can’t raise my head when I’m lying down for 4 months. After 7 months, he still could not turn over to both sides. I still can’t sit up for 9 months, even for a few seconds. After 12 months, they still cannot crawl or sit and move. After 14 months, I still couldn’t grab the sofa and stand up. After 17 months, I still can’t take a few steps on my own.

Fine Motion:

    After 4 months, the line of sight will still not follow your movements from one side to the other, and you cannot hold on to adults’ fingers. After 6 months, I still can’t reach out correctly and consciously grasp something (such as rattle); At 9 months, the toy still cannot be grasped accurately. At 12 months, I still can’t grasp things with my thumb and index finger, and I can’t hold the cup. After 15 months, I still can’t use my index finger to point at things and won’t pile up wood when playing. At the age of 18 months, I still can’t eat by myself with a spoon and can’t make imitations (such as combing my hair or making phone calls).


    After 4 months, he still won’t show a responsive smile. At 6 months, I still can’t laugh, and I can’t use different cries or waves or kicks to show that I want what. At 9 months, I still can’t imitate facial expressions and sounds and can’t interact with myself in the mirror. After 12 months, I still won’t respond to my name, won’t wave goodbye, won’t stretch out my hand to hug. After 15 months, I still can’t understand [no] and other simple words. When you ask [where is XX], I won’t look around for things. At the age of 18 months, I still can’t recognize facial organs, can’t point to things and ask for them, and can’t laugh at interesting things.


If the child’s speech development is obviously behind the development milestone, the child should be taken to the hospital for examination. If the child frequently suffers from ear infection or feels that the child has hearing problems, he should also be examined.

If the child only has the above situation, it does not mean that there is a serious developmental problem, but it is necessary to take the child to see a pediatrician in order to fully evaluate the overall development of the child.

Risk factors leading to stunting:

All babies may suffer from some stunting, but the following babies are at higher risk of developing stunting:

    A premature infant; Infants born with neonatal asphyxia; Infants with congenital defects; Infants who need to be hospitalized due to illness in the first few months; Infants whose mothers have been exposed to prohibited drugs or alcohol during pregnancy; Infants with siblings with significant stunting or autism.

Children with the above conditions can go to the hospital regularly for physical examination when necessary to comprehensively evaluate their development.
