6months milk intake drops

Normal. When they starts solid, their milk intake will definitely decrease. But remember their main is still milk until 1 yrs old. I also noticed my 7 mth old's milk intake decreases. He eats very well & can eat 2 servings of cereal (4 scoops each). Then we went for his jab last week & realised his weight is only 50% percentile of his corrected age. So now I've decreased to 1 serving only. He feeds twice a day, breakfast & dinner. And his milk intake is back to normal. He drinks 180ml per feeding, about 720-900ml per day.
