Hi not more than 40 ml because it will fill their little tummy leaving no space for solids. Breast milk or formula milk will be the water till one year, as the months pass increase the water. Also in the beginning they dont drink more than 1 or 2 tsps. Use teaspoons or small open tumblers, while going out straw bottles.
