查了一下资料，说婴儿不需要果汁，喝多了还有危害。
“Many moms like to think that as soon as their baby turns 6 months of age, they should start giving them juice.This couldn’t be further from the truth. In fact, juice is not necessary for an infant.
Here’s why:
Because of the sugars in juice, it can cause diarrhea.
Too much juice can cause a child to be overweight or obese.
Juice contains sugars and acids that can cause tooth decay.
Giving your baby too much juice can hinder growth and development, and can cause malnutrition and anemia due to lack of nutrients like proteins and complex carbohydrates.
If you are still breastfeeding, juice can cause your baby to nurse less.
