Infants need to be fed more strictly according to their monthly age. Overfeeding beyond their monthly age or feeding in the wrong way will not be beneficial to the baby and will cause trouble to themselves. In general, infants need at least 100 ml of water and 100 calories per kilogram of body weight per day, while formula or breast milk has about 20 calories per 30 ml, so babies need to drink at least 150 ml of milk per kilogram per day. For example, a 5-kg baby should drink 750 ml of milk per day, or 120 ml of milk every 4 hours. For infants who drink mother’s milk, the amount of milk is determined by the frequency of urination (at least 6 times a day) and weight gain. 0～6 months At this time, only breastmilk or breastfed formula is needed because the baby’s intestines are not yet developed enough to accept solid foods, and giving cereal or other solid foods may cause flatulence or soft stools. When young infants are three to four months old, their tongues have a push-out reflex, and they will instinctively push food that is not liquid out of their mouths with their tongues. It is also important to delay the introduction of solid foods to avoid allergies as they grow older. Seven to eight months At five to six months of age, infants begin to show signs that other foods can be added, such as head fixation, loss of the tongue thrust reflex, interest in foods other than milk, looking at other people’s food, and possibly reaching into other people’s plates. At this time, you can try to give paste-like food, such as rice flour, porridge, etc., because they are easy to digest and rarely cause allergic reactions. You can also feed grated bananas, apple juice or pear juice in small amounts at a time, and don’t expect him to eat a lot of it at one time, as at this time, his main source of nutrition is still breastmilk or formula milk. At around seven months, your baby will begin to develop the ability to grasp anything he can see with his fingers and put it in his mouth at the same time, which means he can feed other foods. He can also grasp the feeding spoon with his hand and you have to use the other spoon to feed him; he starts to mimic the chewing movements of adults by moving his upper and lower jaws from side to side. Since he has not yet developed all his teeth to chew his food, it is best to feed him mushy food. Nine to eleven months At this time to let him get used to solid food. Breast milk or formula is still his main source of nutrition; around one year of age, solid foods can make up about 50 percent of his nutritional sources. His eating skills are much improved and he has more teeth, allowing him to swallow food more easily. Spaghetti, small pieces of vegetables, and crackers can be given at this time, and table foods can be given gradually after one year of age. Dietary information for infants and toddlers within the first week of life After six months of age, when your baby can control the bobbing of his head, sit upright without wobbling, have a chewing action, and can swallow food after it is delivered to his mouth, he can start to feed complementary foods. The addition of complementary foods should be gradual, do not mix many new foods, add only one new food at a time, wait for a week for your baby to get used to it, and then add another new food, and mix the foods only after each one can be adapted. Most babies do not eat well on the first try, but after a few more tries without pressure, most babies will be able to accept new foods. Zero to two years old should establish good eating habits Nutrition in infancy and early childhood has a great deal to do with future growth, development, and illness. Parents may differ in their subjective determination of how much their babies eat. In fact, the growth of infants and toddlers should be measured by observing them over a period of time with objective criteria. Parents who are troubled by infant and toddler feeding may wish to consult a pediatrician for objective assessment and practical advice.
