Nail biting, hair twirling, nose picking, thumb sucking etc are some of the common habits that are found in children. Most parents constantly complain about these habits that their children have. However, I have realized that it is only a phase for children and that with due time, it fades away when you explain its repercussions to them.
Children are usually unaware of this behavior and that they do not even realize that they are doing something that is not a good habit. Nail biting is one of the most common bad habits that are found in children. These are considered as signs of nervousness. Even nervous adults bite their nails.
There is some research that shows that around more than half percent of children population between the age of five and ten bite their nails. However, most schools are very particular about nail cutting and punish the students if they grow their nails. This is somewhat helpful for children who bite their nails.
As parents one should be patient and calm and make the child realize that it is bad for health when they bite their nails. Praise them or gift them if they do not bite their nails for a specific time frame. Make sure that your child washes his or her hands before meals. Check their nails regularly and make up stories to tell them how nail biting can be dangerous.
There is a study that also shows that even though both boys and girls appear equally prone to this habit, as they get older, boys are more likely to be nail biters. I do not know about the psychology behind this research but the fact lies in being responsible parents who do not encourage these habits and take immediate precautions to curb it.
