Why do people wear bibs?

Babies wear bibs, to stop the food they dribble or miss by eating staining their clothes, they can also wear bibs to stop getting their clothes wet by dribbling, this is because if they dribble and get their clothes wet, it can cause the baby to become ill. Babies also wear bibs because if you are feeding them by a bottle they may not be able to swallow all the milk at once so they spit it back out. There are many reasons for a baby/toddler to wear a bib, another reason is when you burb them they may be sick so the bib is there to stop them being sick on their clothes they are wearing.
