Ten-month-old babies need at least 750-800mL of milk a day, preferably up to 800mL, in order to meet the baby’s need for protein-rich nutrients. It is generally recommended that when choosing milk powder for 10-month-old babies, it is advisable to choose some milk powder that is suitable for the baby’s age to drink, so as to provide the child with sufficient required nutrients. At the same time, 10-month-old babies can add complementary foods in moderation, and can be recommended to add about four meals of dairy on top of the basic milk supply. Therefore, it is recommended that the amount of milk in a day is about 750-800 ml to ensure that the child can get sufficient milk supply to ensure healthy growth and development. If you have any other questions, it is recommended that you consult a medical professional for guidance.
