Newborns can only smell a few different things, such as their mother’s body smell. Sense of smell improves up to about the age of eight. But from the age of 20 (or even 15, according to some studies), the sense gently declines. Yet some studies have found that children can’t detect certain musk odours until they reach puberty.
