Why Do Kids Bite Their Nails?

Almost 60 percent of the total teens and kids bite their nails, but this habit is developed over time due to various factors.

Whether your kid is doing it on purpose or without knowledge due to certain reasons is something to think about. 

A few reasons for biting nails are shared here. Find which one is your kid’s reason to chew off the nails and skin.


It may seem weird, but sometimes, kids do it to get attention. Every time they put their finger or thumb in their mouth, you ask them not to do it. So kids learn that this is a way to get your attention.  


You might be thinking that what are kids stressed about? We provide them with everything they need then what they might want. But a kid’s life is not easy. They are dependent on you and look up to you for everything.

You decide their playtime, where they play, what they eat, how they eat it, and almost everything. If anything goes wrong, kids get stressed.

Be it tearing their pants while playing or breaking the glass vase you love. When they are stressed, they bite nails. 


Playing can be boring too. When kids have nothing to do, they start picking on their noses or biting their nails.


It is a common habit in kids to feel relaxed after doing these things, whether it is biting their nails, playing with their hairs, or sucking their thumbs. 


Growing up is not easy. Kids learn new things; they come across new lessons, people, concepts, etc, making them anxious. When they can’t understand a thing and are stressed, they bite their nails. 

Is It Something To Be Worried About?

As parents, you are stressed and anxious about many things, such as work, family, life, and raising kids. But these tensions are invisible to kids.

In the same way, learning new things daily, growing up, seeing the world in a different light, encountering sensory developments is an anxious process. As a parent, you don’t understand as they are invisible to you. 

Since nail-biting results from anxiety and stress most of the time, parents often worry about their kids having any disorder. To know if it is a serious problem or not, you must monitor your kid.

Whether he starts biting the nails after encountering a particular situation, watching a specific cartoon, when talking about a certain person or topic, or the nail-biting is just a habit.  

If the kid is biting nails while laughing or playing and doesn’t let go of the finger at any time, it is just a habit. In any other case, you must check out your kid’s hands.

See if they don’t realize that their finger has started bleeding and they still keep biting it, the skin is torn, but they don’t let go, their nails are almost non-existent, and the skin is ragged.

Such self-destructing nail-biting habits are not normal, and your kid is going through stress. 

Consult the doctor if your kid is not sleeping well and keep biting the nails, if he is jumpy and jittery all the time, and this nail-biting habit has suddenly surfaced.

You can also talk to your kid about having any problem. But it requires building confidence in them that you mean good.

Engage Them In Fun Activities

Boredom is also why kids bite their nails, so engage kids in some fun activities. You can use coloring books, jigsaw puzzles, making forts, etc. Take kids aged 6-12 to the park or on your lawn and play some fun games.

Use Nail Polish

If your toddler is not giving up on nail-biting, it is time to take some tough steps. Apply bite-averting nail polish and let them know why you are doing it.
