1.Objective 1.Supply food other than mother’s milk and cow’s milk, so that the baby can adapt to the new food. 2.To make up for the lack of nutrients in milk. 3.Training baby’s chewing and swallowing ability, as a preparation for weaning. Principles 1. Add only one new food at a time and add another one after adaptation (the original food added can continue to be eaten). 2. Make sure to add new foods gradually from small amounts. 3, from liquid → paste → semi-solid → solid, progressive practice swallowing. 4. Pay attention to the skin and stool condition. If skin allergy or diarrhea is found, suspend the new food. 5. It is more appropriate to give between feedings or when you are hungry. Be patient when feeding. 6.Be sure to wash hands, equipment and food before making side dishes. 7. The baby should be in a sitting or semi-sitting position. 8.Mothers should feed in a relaxed and happy manner so as not to affect the baby’s acceptance. If the baby refuses to eat, please do not force him/her to try again the next day. If he/she still does not eat after two or three days, please suspend and try again at intervals.
