My baby chew her lower lip and she is 2 year old when she stop this habit

A. Hello good morning !! If the baby bites lips as a habit observe the baby behaviour whether doing normal time or due to fear or anxious some might bite lips ,nails in the feel of relief or to deviate from anxiety. As the baby is two years old ,engage in other activities and deviate from biting lips by making her talk or playing ,showing things.
