Good morning parents. My son is just 6 months old but sometime his breath is smelly. I clean his mouth with a small soft cotton cloth. Is it normal to have bad smell?

Hi, It can be because of some respiratory infection and also because of the environment is capable of sustaining the same bacteria that causes bad breath in adults. In babies, dryness in mouth also causes bad breath. Since, babies keep their mouth open, the environment in the mouth becomes devoid of oxygen resulting in the reproducing of aerobic bacteria in the mouth that causes bad breath. So, you make sure, you clean the gums and tongue of the baby with wet cotton ball and keep the baby hydrated. Also, because babies put their toys in their mouth so bacteria from the toys reach their mouth and not only cause bad breath but can also cause stomach flu in babies.
