The baby is already three years old, at which point their brain development is quite complete. From the perspective of development speed, after the age of three, the baby's brain development has become relatively slow. But at this time, it is still important to pay attention to the baby's daily situation. So, what is the reason for a three-year-old baby having black stool?
At the age of three, a baby's stool is black, which is different from the color of the word 'stool'. Normal stool is a yellow color, after all, at this point the baby is already eating normally like an adult, but the color of the stool pulled out is black, which is definitely abnormal and needs to be investigated for the reason.
From the specific reasons, parents should think carefully about whether their babies have eaten black food before. Of course, it is not necessarily black, and dark food can also cause three-year-old babies to have black stools. Of course, there are some foods, such as duck blood, which are also the reasons why babies have black stools.
Of course, due to food reasons, if a three-year-old baby has black stool, there is no need to worry. After waiting for a period of time, the baby's stool will return to normal, which is only one or two days. It should be noted that the cause of the case, such as gastrointestinal bleeding, should be taken into account. Once the baby's black stool lasts for a long time, attention should be paid.
