Our expert says:
Siya, it’s very young for a child to start biting his nails, but it might just be a bad habit. It might be a sign of stress or inner turmoil, but I doubt it. The best would be to get something that tastes awful (aloe, etc) and apply it to his nails. It is available in various forms at the pharmacy and hopefully it will stop him from biting his nails. Make sure that you make him aware of when he is biting his nails and that it’s not a good thing to do, but never scold him. Good luck.
