How come kids don't snore but adults do? what changes happen to make us snore and why are some people louder than others?

Kids do snore too: But reasons for snoring in kids are bit different, although overweight/obesity with more fat deposition in the neck area is the main reason adults snore, in kids this is less common than enlarged adenoids that can block the airways partially and cause snoring. Either way, weight reduction if overweight/obese at any age is needed to control snoring together with treating the enlarged adenoids
