Weight of new born babies is calculated to be 80% water, and therefore they are a risk group that needs to be watched in terms of hydration.

Babies, during the first six months of their lives, hardly ever need any additional water intake besides that provided by mother’s milk, except in hot climatic conditions or water loss due to other reasons. Water supplements become necessary as the child grows. Most of the child’s water needs from months 6 to 12 will be satisfied through feeding bottle intake.
