Only a doctor can find the root of the problem. To start the baby should be examined by a pediatrician.
Fatigue often accompanies anemia, microbial or viral infections (for example, influenza, hepatitis) and helminth infections. Most often, except for lethargy and drowsiness, there are associated symptoms: digestive problems, headache, poor appetite, fever.
If the examination did not reveal any diseases and the little tot looks tired for more than 2 weeks even after a good rest, it is necessary to contact a neurologist or a psychologist.
If there is no physiological basis for fatigue, this means that its causes are psychological. Most likely, the baby has become depressed, although it catches up with children much less frequently than adults.
Forces of the child can undermine any, not just drastic changes. The overwhelming majority of children will react sharply to the appearance of a second child in the family, the death of a pet, parental conflicts, traveling to a country with a different climate, excessive loads in kindergarten.
But the feeling of depression can also occur at the slightest change in the daily regimen.
The baby, discouraged, loses his appetite and interest in his hobbies, becomes sluggish and sleepy. To cope with the difficulties of the child will help the advice of a psychologist. Your task is to eliminate the main cause of depression: reduce the workload, restore a positive atmosphere in the family, etc. At the same time, it is important to clearly regulate the lifestyle of the baby and not retreat from the accepted rules: let the crumb always eat in the same place, wake up, bathe and goes to bed at the same hour, for the night listens to a fairy tale or drinks a glass of kefir.
It is very important to create favorable conditions for sleep, so the evening is better to set aside calm games. At the age of 3-4 years, the baby must sleep at least 10-12 hours a night, and a 2-hour siesta is obligatory during the day.
There is a fairly large group of drugs that give energy. Their composition may include minerals (magnesium, calcium, iron, zinc, copper), vitamins (primarily vitamin C), amino acids and stimulating components, such as eleutherococcus or glutamic acid: they strengthen the work of the nervous system and give strength.
Sometimes it is really possible to solve the problem with the aforementioned remedies, considering that almost every tenth child under 4 years old has fatigue caused by a lack of iron. In this case, a properly selected vitamin-mineral drug and the required dose will quickly improve the situation.
However, to decide whether the pill will benefit the crumbs, only the doctor should, because in some cases invigorating means are useless and even harmful. So, if a child is experiencing serious family conflicts or problems in kindergarten, such drugs will only increase nervous excitement. In this scenario, the doctor will use a different tactic.
For example, he may advise adding to the menu more fruits and vegetables rich in vitamin C (oranges, kiwi, cabbage, spinach) and meat products – the main source of iron.
