The smell of alcohol in infants has some effects, but they are very small and rarely cause serious conditions. First, it can cause coughing in infants because the smell of alcohol is relatively heavy and can cause coughing if it is close to the infant. Secondly, it can cause vomiting. Some infants are very sensitive to the smell of alcohol and may suffer from nausea and vomiting. Sometimes there is also an allergic situation, which is very rare. Babies are allergic to alcohol and can get a rash after smelling alcohol. If there is the smell of alcohol, try to isolate the baby.
