一岁半如果不是过敏严重必须需要喝水解奶粉的特殊宝宝（很少很少），可以喝纯牛奶不喝配方奶，配方奶除了贵外还不如纯牛奶好。什么维生素矿物质等等都是智商税！一岁以后主食吃好营养丰富，奶就是辅食，最大的作用就是补钙！其他乱七八糟的补钙的钱也省了！
One-and-a-half years of age, if it is not a special child who has to drink hydrolysis powder, it can drink pure milk instead of formula, which is better than pure milk than expensive.
