There are individual differences in the amount of milk powder for one year old babies, which need to be analyzed on a case-by-case basis, such as formula milk feeding is usually about 450-600ml per day, and for mixed feeding the amount of formula milk needs to be decided according to the amount of breast milk. For 1 year old babies, breastfeeding, formula feeding or mixed feeding are usually adopted. Since the amount of breastmilk and the baby’s demand are different, there are individual differences in the amount of formula fed. For babies in this age group who are fed with formula milk, the amount of milk powder they drink is usually about 450-600ml, and the amount of milk powder they drink is about 200-250ml per day for about 2-3 feeds per day. For babies who are still breastfed and can meet their growth and development needs, there is no need to add extra formula milk. For mixed feeding babies, the amount of formula to be added depends on the amount of breastmilk. Generally speaking, if the baby is developing normally and gaining weight well, the amount of formula is considered appropriate. It is recommended to seek medical advice from a specialist if necessary.
