My 9 months old son is feeling difficult to breath at night as our house is too cold. we are using nasal drop every night. is there any side effects for infants using nasal drop very often like this?

A. Snoring in kids is common,this may be due to low laryngeal muscle tone or allergic rhinitis ,or due to Adenoid hypertrophy. You must go for X ray soft tissue neck lateral view. Consult ENT specialist once
