My 5 month old is almost always snotty. you can always here it in his nose, why is that? his doctor says hes complexity healthy but rarely do i hear him this snotty. been like that since the day he was born?

The nasal passages of small infants are relatively tiny. Even small amounts of mucus can plug them. Fragrances/dust/odors from soaps in their bed linen or clothing all can trigger an outpouring of mucus designed to wash them away. Gentile removal using nasal saline and a bulb suction helps as does removing all triggering factors. It is less a problem when they get bigger/older.

The use of nasal saline drops is often effective. Keep his environment clean and smoke free. If he has had pneumonia or neonatal distress, discuss ciliary dysfunction and screening with your Pediatrician. Watch for any signs of distress. Most likely he is healthy and this will self resolve.
