Generally speaking, it is best not to drink milk for babies below 1, because milk contains a lot of protein and minerals, and there are too few complex unsaturated fatty acids and trace elements, which are not easy to be digested and absorbed by the baby's delicate intestine, which is not conducive to the baby's growth and development. In addition, milk may also be the cause of milk protein allergy.

2. A baby over six months old can let him adapt to milk slowly, provided that the baby has no signs of allergy after drinking milk.

3. Start with a spoonful, and then gradually increase to cook cereal with milk. When the baby is 2 years old, you can give milk and dairy products regularly, about 300 ~ 350 grams a day. So a one-year-old baby can drink milk.
