While adults constantly need a reminder to drink water, when it comes to babies, then it is quite another story. Their body is not sufficiently developed for water consumption, and in extreme cases it can be very dangerous.
The body of an average, healthy adult is composed of 55-60 percent water. On the other hand, the body of an average baby is about 75 percent water. This difference is the reason why babies should not drink water before they are at least 6 months old. The kidneys have a limit on how much water they can bear if you cross that border, excess water will cross into the bloodstream where it dilutes the salt or sodium in your blood. This creates a risk of hyponatraemia, a condition that occurs when cells try to restore salt levels to normal by absorbing excess water, thereby swelling cells. It causes complications such as nausea, spasms and cramps in the muscles. The condition can escalate if you continue to drink water to water poisoning, occurs when brain cells emerge and this can lead to dizziness, brain damage, and death.
The kidneys of newborns are not developed enough and are twice as small as the kidneys of adults. They can not filter the water so that any water ends up in their system of circulation, where water increases by 7 to 8 percent.
Therefore, carefully with the water and teas in babies, and more you can learn from the video:
