If you notice that your child is biting his nails, do not shame him, do not ridicule him, do not yell at him or punish him in any other way.
Such behavior on the part of an adult will only cause additional stress for the child. As a result, a feeling of helplessness, anxiety and hopelessness will arise, and self-esteem will rapidly plummet.
Instead, try what experts call positive reinforcement.
How to Help Your Child Stop Biting Their Nails
Try to turn giving up a bad habit into an exciting game, at the end of which the child will receive a prize.
The first step is to explain to your son or daughter why it is worth trying hard to stop biting their nails and promise him or her that you will help him or her cope with it.
Now is the time to explain the rules. Explain to your child that he must stay without the bad habit for a certain number of days, after which he will receive a prize.
Each successful day can be celebrated by issuing colorful stickers, labels, or marking it on a calendar.
Create several levels of difficulty: three days, one week, two weeks and one month. At the end of each period, the baby should receive a reward.
Prizes can include treats, toys, or visits to events such as the circus, trampoline center, or amusement park.
What to do if a child loses
If your child has lost his temper, get rid of the idea of scolding or shaming him. You should console the little one and support his desire to hold out as long as necessary next time.

Onychophagia is a mental disorder characterized by obsessive nail biting.
