If your baby has bad breath, first of all, you should exclude the causes in the mouth. If you do not brush your teeth in time after eating, if there is accumulated milk or accumulated food residue in the mouth that cannot be removed in time, or if there are cavities, inflamed gums and bleeding, oral odor will appear, while the pain in the mouth will also cause your baby to resist eating. In this case, you should take your baby to the stomatology department in time to treat oral disorders. Furthermore, chronic tonsillitis also often has bad breath. If you still have bad breath after ruling out such disorders, it is likely that there is food accumulation in the stomach, which is commonly referred to as eating too much. If you eat more food than your child can digest, the food residue will decompose in the stomach and heat will build up in the stomach and intestines, leading to the occurrence of bad breath and constipation. The solution is to improve the baby’s diet structure, not to favor meat, eggs and milk and other high-calorie foods, but to eat more vegetables and fruits to increase fiber and promote intestinal peristalsis. There is also a key point is that some parents have the wrong idea that “children are growing, they must eat more, otherwise they can’t keep up with the nutrition”, once the child does not want to eat parents will chase and feed the child to eat, according to their own judgment to decide how much the child should eat, often leading to the occurrence of food accumulation, making the child have breath, constipation This often leads to food stagnation, making the child suffer from bad breath, constipation, and poor eating habits. So don’t force your child to eat when you eat. As the saying goes, “To have a child’s well-being, it takes three parts of hunger and cold”.
