Infant Hydration Needs and Water Intake Recommendations
Infants and young children are at higher risk of dehydration due to their unique physiology, including immature kidneys and a higher body water content relative to their size. Studies show that as infants age, their total water intake (TWI) increases, but many still do not meet the recommended adequate intake (AI) for their age group. For example, research found that the percentage of children not meeting AI increased from 10% in younger infants to 88% in older toddlers, with milk and milk products being the main contributors to TWI, and plain water intake increasing with age. Fruits and vegetables also contribute to water intake after six months of age, but overall, there is a strong discrepancy between actual and recommended water intakes in young children, highlighting the need for strategies to increase water consumption in this population 17.
Risks of Dehydration and Overhydration in Infants
Dehydration in infants can have serious health consequences, including hypernatremic dehydration, which can lead to critical illness or even death if not promptly treated. Cases of severe dehydration have been reported in breastfed infants, emphasizing the importance of monitoring hydration status, especially in the first weeks of life . On the other hand, water intoxication is rare but can occur in exceptional circumstances, such as excessive water intake or improper formula preparation .
Hydration Management in Preterm and Low Birth-Weight Infants
Preterm and low birth-weight infants have special hydration needs due to their inability to regulate water intake and higher insensible water losses. Research indicates that careful restriction of water intake in premature infants can reduce the risks of certain complications, such as patent ductus arteriosus and necrotizing enterocolitis, without significantly increasing the risk of dehydration. However, each infant's needs must be assessed individually, and frequent monitoring is essential to avoid both dehydration and overhydration 34.
Water Safety and Sources for Infants
Safe water supply is a fundamental public health concern, especially for infants and young children. As children grow, the proportion of plain water in their diet increases, with about half of older toddlers' water intake coming from tap water. Ensuring access to safe, clean drinking water is crucial, as is educating parents and caregivers about healthy hydration practices and the risks associated with unsafe water sources or inappropriate beverages 157.
Public Health and Education on Infant Hydration
Most children worldwide do not meet recommended water intake levels, often due to limited access to safe water, lack of availability in schools, and insufficient education on healthy hydration. Public health policies should focus on improving access to safe water and providing clear, evidence-based guidance to parents and caregivers. Recommendations should be regularly updated and communicated to help families make informed decisions about infant hydration 57.
Conclusion
Infant hydration is a critical aspect of child health, requiring careful attention to both the quantity and safety of water intake. While breast milk and formula are primary sources of hydration in early infancy, the gradual introduction of plain water and water-rich foods becomes important as children grow. Ensuring safe water sources, monitoring hydration status, and providing clear public health guidance are essential steps to protect infants and young children from the risks of dehydration and water-related illnesses 1234+2 MORE.

Total water intake and its contributors in infants and young children
Actual and recommended water intakes for infants and young children differ significantly, with milk and milk products being the main contributors to total intake.
Assessing Hot Water Reconstitution Practices and Labeling of Powdered Infant Formula to Enhance Microbial Safety Involving Cronobacter spp.
Using small volumes of hot water in small glass bottles and recombining powdered infant formula with it when it cools to 165F (73.8C) can ensure microbial safety and ensure a minimum treatment temperature of 158F (70C) for high-risk infants.
