The main causes of sticky and starchy saliva in infants include the following: First, it is caused by the type of diet. Because infants are mainly fed breast milk or formula, these foods tend to be high in protein and sugar, which can cause the symptoms of sticky and starchy saliva. As the amount of complementary foods consumed increases, the sticky and stringy drooling will subside. Secondly, the symptoms are caused by stomach heat. If the infant has stomach heat, it may cause sticky and stringy saliva, bad breath and dry stools. Stomach heat can be treated promptly, such as applying Wang’s Baochi Pills, or boiling dandelion in water for infants to drink.
