In 4 months the child's development to a new level: in the psyche and physiology crumbs comeSerious changes. It is convenient to read on the video with the features of the development of a four-month-old baby or listen to lectures of the pediatrician Komarovsky.

Physiological indicators of a four-month-old baby

In modern pediatric practice, there are two types of tables and standards - domestic and international. The main parameters on which these standards are based are reduced to measuring several physical indicators:

  • growth;
  • weight;
  • of the head circumference;
  • chest circumference.

These indicators depend on the height and weight that the baby had at birth. According domestic pediatric school, the threshold levels of these parameters in a 4-month-old baby following:

  • weight for boys - 6-7,6 kg 5,7-7,1 kg for girls, the tolerance to 0,7 kg( At the birth of a child not on time);
  • height in boys is 58.7-64.5 cm, in girls these figures are 58.5-64 cm;
  • head circumference 39-43.5 cm;
  • chest circumference 38,6-44,6 cm.
Child at the pediatrician At one year of age the child should regularly visit the pediatrician, the doctor can track compliance with generally accepted standards of child development. Of course, very strict on the indicators to be guided not necessary, but a rough idea of ​​parents and the local doctor they will

international standards differ from those taken from us. Error by gender are the same, but the parameters of international standards themselves have a deviation in a big way:

  • weight - 6,2-7,6 kg
  • growth - 57,8-68 cm;
  • head circumference - 38.1-44 cm;.
  • chest circumference 37,3-45,2 cm

Deviations Rostov-weights from

regulations baby 4 months, gaining weight in direct relation to such factors as:

  • diet;
  • heredity;
  • during pregnancy;
  • physiological development.
If childbirth has passed before the term, the baby may lag behind the weight-weight indicators from normal values. At 4 months he can not catch up with his peers born in time and "level off" only by the 2nd year of life. The same applies to children who were born or toddlers who were born very large for hereditary reasons. Their indicators differ from the age norm, however, in a larger direction.

This situation is not a reason for panic. More meaningful in this case will be an analysis of the general condition of the crumbs, but if the weights change more or less by 1 kg, you should pay attention to this. Both cases - an occasion to go to a specialist and change the ration of a crumb, since they are fraught with:

  • obesity( weight gain);
  • rickets and hypoxia( weight reduction).

Mode for a 4-month-old child: do you need or not?

The physiology of the child and its features

4-5 months is the time when the child stops wearing scratches, even if at an earlier age it was possible to put them on, so the length of the nails should be monitored. The nails of in children, although soft, but with breakage form sharp surfaces, with which the baby can easily scratch both himself and his mother.

The nervous system of a four-month-old baby is very sensitive, he reacts violently to irritants, both to positive ones( for example, to address him by name), and to negative ones( for example, he draws to the mother of the handle, and she passes by without paying attention to it).

In 4 months old crumbs will really like songs and rhymes, music games that are combined with a massage. When addressing a child by name and with a smile, he happily responds with a smile and a walking ( can try to pronounce individual syllables), i.e. Already clearly recognizes his name. Some babies out of love for pronouncing sounds can overstress and turn pink, this is okay, they just got carried away by the process.

Power and its features

By this age, you can switch to 5 times a day, , in which case the last feeding will take about 20 hours. In this case, the baby should sleep for about 10 hours in a row, which is why the diet for breastfeeding should be adjusted. However, not all babies in 4 months can withstand a prolonged hunger pause, some children still ask for food - you can try to drink them with children's tea or diluted juice. Perhaps the baby wakes up because she wants to drink, but if that's not enough, of course, starving the baby is not worth it. Gradually, it is still necessary to wean him from breastfeeding at night - for example, after feeding him at the last evening meal.

If the baby is on breastfeeding, the lure can not be introduced. If the crumb is artificial, or the diet is mixed, you need to gradually accustom your child to "adult" food. You can start with vegetable purees. Some babies eat well with spoons from the first samples, some do not perceive such a way of eating. The baby can be given a play with a plastic spoon for children to get used to. This will facilitate its subsequent feeding.

Between feedings( if the baby is healthy and born on time) there should be at least four hours of , a deviation of up to half an hour is permissible, but it is better to avoid it by full feeding at every meal. If the baby lags behind in weight gain, try switching to a 6-time diet.
