How many oz of water does a breast fed 11 month baby should consume per day?

Depends on how fed: Every infant is different. Exclusively breastfed infants do not need extra water. If using other formula, they may need water. Worth reviewing with your pediatrician.

Water: Alternative fluids for breast milk include water, juices and milk. At one year of age a child is transitioning to more independent eating habits and the amount and variety of fluids are at your child's choosing. Water is a great resource for a child to enjoy and much healthier than sugary drinks. So let your child eat normally and drink as much water as desired. No max or min .

Should=none: A breast fed baby requires no supplemental water. It is often used as a way to let non-mothers participate in babies care, but they have no need for water. When a baby is wetting diapers at least every 6 hours they are demonstrating that they have a normal fluid balance.
