Hello, question asker. Let me give you a warm hug first.
I can see what the issue is. From what you've said, I can understand why you're confused. Here are some references that might help:
1. Get a physical exam at a regular hospital.
If your child is biting their nails, it's a good idea to take them to a regular hospital for a check-up. This will help to rule out any physical causes and also check if there's a lack of trace elements. You can also ask the doctor for advice based on your child's condition.
2. Behavior habits
Sometimes kids' behavior is also unconscious. It's like when we unconsciously walk around the telephone cord when making a landline call or unconsciously draw a lot of shapes when we have a pen in our hand. Kids like to explore when they're young. They want to pick up and bite anything around them, which is also how they get to know the world. At first, kids may just be curious, and then unconsciously develop these behaviors. For kids, subconsciously they cannot judge whether this is good or bad.
3. Stress
When kids feel nervous, they'll often unconsciously do things like clasp their hands, touch their ears, or clench their fists. It's a way of hiding their emotions. And when they feel like they're in danger, they'll sometimes exhibit these behaviors to protect themselves.
We adults sometimes do it too, but we don't always notice.
To sum up, I'd say the first thing to do is check if the child is lacking trace elements in the body. Secondly, you can observe your child more and chat with her in a relaxed way, rather than stopping her when she wants to bite her fingernails. This will make her more nervous and she'll think she's done something wrong, which will make her blame herself.
At this point, we just need to be patient. We don't want to scare her; we just need to explain the facts, like how biting your nails can lead to bacteria getting into your mouth and how it's not a good look for girls. At the same time, help your child find ways to distract herself.
If you're there for your child, you can also help her keep a record or let her do it herself. For example, note how many times she behaves this way in a day. We also need to praise and encourage her more and believe that she can slowly break this habit. At the same time, you should also talk to the teacher about your child's situation at school and whether there are any other stressors.
It's also a good idea to chat with your child more, in a relaxed setting like nature or the great outdoors. You can ask them about what happened. Their memory might be a bit distorted, but that's not the point. What matters is that they open up and talk about why they're acting this way. If they're ready to talk, don't push them if they're not.
I hope these tips are helpful for you. I'm sure you'll be able to resolve your concerns soon. I wish your baby a healthy and happy growth, and I wish you happiness. The world loves you, and we're here for you.

I understand your concern. It's not necessarily about parenting; sometimes kids develop habits like nailbiting due to stress or boredom, and it might help to explore what triggers this behavior in her.
It sounds challenging. Nailbiting can be a sign of anxiety or just a habit that's developed over time. Maybe consider talking to her about how she feels and see if there's anything bothering her.
Your situation is tough. Try not to blame yourself. Children can have habits that are hard to break. Have you thought about speaking with a pediatrician or child psychologist for advice?
I can see you're worried. This could be a way for her to cope with emotions or stress. Perhaps introducing alternative activities that keep her hands busy might help reduce the habit.
This must be frustrating for you. Sometimes kids bite nails without realizing it. You might want to look into gentle reminders or rewards for when she refrains from biting her nails.
