Colic of the infant, one of the most common conditions in newborns, is one of the great concerns of parents, who do not know how to calm the uncontrollable crying of their children. Colic affects infants, infants less than three months old, and can be defined as episodes of intense crying that can last for about two hours a day, several days a week. But how to calm the baby? What do you do to reassure and relieve him? Studies that demonstrate the efficacy of reuteri According to a study by different pediatricians at the University of Turin (Italy) in 2010, Lactobacillus reuteri reduces episodes of uncontrolled crying in infants in 74% of cases, after having been given for a week. To reach such a conclusion, pediatricians administered 10 drops of Lactobacillus reuteri daily to 25 infants with colic and 10 drops of placebo to 25 more infants for 21 consecutive days. Infants who took Lactobacillus reuteri reduced episodes of uncontrollable crying considerably. In 2007, another study was conducted to evaluate the effect on baby cramps of Lactobacillus reuteri and Simethicone, an antiflatulent that eliminates abdominal discomfort. In this case, a significant reduction of uncontrollable crying was also observed in infants who took Lactobacillus reuteri versus simethicone, which was not as effective. The efficacy of Lactobacillus reuteri proves that it can be a good way to treat colic of the infant, since no side effects have been demonstrated in the treatment. However, it should always be done under pediatrician approval. In any case, it is necessary to remember that daily actions can also be taken to prevent colic of the baby without being necessary the administration of Lactobacillus reuteri. For example, some studies have shown that carrying the baby upright, in the arms, is a good measure of prevention against colic. It is also useful to protect the newborn from excessive stimulation, often caused by the high number of visits that accumulate at home during the first few weeks after the baby's birth, with voices, annoyances and a lot of environmental noise. Finally, massages to relieve colic are also very useful.
