When making apple puree, it must be suitable for babies over 6-8 months old, and should not be taken prematurely. Generally, before making apple puree, babies must have eaten fixed complementary foods, such as rice flour and egg yolk. Attention must be paid to the addition of complementary foods, from one to many, from thin to thick, not quick and demanding. When babies have no problems after eating rice flour and egg yolk, they can add apple puree as appropriate. You can cut the apple into small pieces, steam it in a pot for 8- 10 minutes, then crush it with a spoon or other tools, and then feed it to your baby. When eating for the first time, you must eat less, not too much, and observe whether there is diarrhea or constipation in the process of eating. Boiled and steamed apple puree can treat children's diarrhea. If children have mild diarrhea, you can try this method.
