The World Health Organization recommends that children begin to add complementary foods 6 months after birth, and the general recommended range is 4-6 months after birth, depending on each baby’s level of development. If you observe that your baby’s neck becomes strong, he can sit up with a little support, hold his head up steadily, his sucking and tongue reflex gradually disappears, or there are teeth grinding, then you can add complementary foods. Fruit puree is an important type of complementary food, so does it need to be steamed and fed to babies? Usually, fresh fruits are washed and peeled, then scraped into puree with a small spoon and fed to your baby, especially for apples. Generally speaking, it is not necessary to steam the puree, as raw food is good for the retention of vitamin C in it. However, for babies with weak spleen and stomach and cold body, it is best to feed them after steaming to avoid diarrhea. In addition, when adding complementary foods to your baby, you should add one at a time, from little to much, and try a small amount for the first time to see if your baby is tolerant or even allergic to it. If you choose to buy packaged purees, there are also options for allergy-prone babies, but be sure to choose a reliable brand and pay attention to storage methods.
