Child development in months to a year


During the first 12 months the child develops especially actively. And although all the little ones go through different stages of development according to their individual schedule, there are some common signs common to most children of the same age. To determine whether the baby is developing normally and whether it is necessary to inform the pediatrician about any problems, parents should know how to grow and what skills the baby acquires in the first year of life.

Baby crawls
Parents need to know whether the child develops in accordance with age in order to consult a specialist in case of deviations.

Child development indicators

First of all, assess the physical development of the baby, the indicators of which are:

  1. The weight of the child. This indicator is very important for the baby. In the first days after childbirth, the baby loses a bit of weight in normal conditions, but then it only has to add. Usually, the child's weight becomes twice the mass at birth by 6 months of age and three times more by 12 months.
  2. The growth of the baby, the indicators of the circumference of the head and chest. During the first year, the child grows in length by about 25-27 centimeters, while in the first months the baby grows especially actively, adding 3 cm of growth, and in the second half of the year - only 1-2 cm each month.
  3. Static and motor functions. Assess the child's ability to hold his head, grab and hold objects, roll over, sit, crawl, stand on legs, walk and others.
  4. The presence of teeth. The first teeth (incisors at the bottom) usually appear by 6 months of age. The normal number of teeth for the baby is calculated by subtracting the number from the age in months. By the age of most babies, 8 teeth are cut.

Emotional and mental development of the crumbs is estimated by the following indicators:

  1. Emotions baby. A monthly baby begins to smile, and at 3 months of age he becomes animated when an adult applies. The grown-up tot shows more and more emotions, both negative and positive.
  2. Speech development. The first sounds, which makes a crumb, are grunting and sniffing, but by the end of the first month the baby begins to roar. As the baby grows, it first begins to babble, and then utters its first words. By the year in the speech of the baby have an average of about ten words.
  3. Manipulations with toys and games. At first, the baby grabs the toys reflexively, but later begins to capture them purposefully. Growing up, the peanut studies their properties and learns the different ways of playing games.
  4. Understanding adult speech and intonation - starts at 6 months of age. The child begins to react to the words of an adult, if they are accompanied by gestures, learns his name, finds with his eyes familiar objects in response to an adult's question.

Immediately after birth, the baby begins to adapt to the new conditions of life, and his parents - to their new responsibilities. The main need of the baby during this period is physical contact with the mother.

Newborn child
The first reflexes are necessarily checked by the pediatrician.
  • The crumb spends most of the time in a dream. The baby’s sleep is deep when the body of the baby is completely relaxed and the eyes are closed, as well as shallow, in which the baby’s limbs can move and the breathing is uneven. When feeding a newborn can nap.
  • The baby responds with crying to cold, hunger, pain, wet diaper, heat and other irritants.
  • In a child, unconditional reflexes of grasping, searching, swimming, walking and sucking are noted. Their presence must be checked by pediatricians. Some of these reflexes disappear with time.
  • During this period, the nutrition of the baby is very important, the best option for which is mother's milk. The baby eats very often (usually with an interval of 1-2 hours), including at night.
  • If you put the baby on the tummy, the baby will try to raise his head. Some kids do it for a few seconds.
  • The child can hold his gaze on a stationary object, as well as respond to the appearance of a sharp sound.
