Create a relaxed, warm and comfortable family environment for babies, so that they can relax when they are nervous, depressed and anxious. Anger and reprimand will only aggravate the baby's pressure, so be calm with understanding and patience.
Arrange interesting activities
When babies are bored, they may get into the habit of eating their fingers. In order to distract them, we can arrange some interesting activities for them, such as playing with peers, cultivating hobbies and making them forget the impulse to eat their fingers.
Accompany a baby
Being with the baby is the key. Use their free time to interact with them, and make them forget the habit of eating fingers in happy games by talking, singing, playing with building blocks or reading books. As time goes on, the baby's interest in eating fingers will naturally decrease.
