How did the child's mouth crack?

There may be many reasons for a child's cracked mouth. Here are some common reasons:

1. Dry weather: In a dry climate, children's lips easily lose moisture and become dry.

2. Lack of water: If children don't drink enough water, their bodies will be short of water and their lips will be dry.

3. Excessive lip licking: Some children will lick their lips unconsciously, which will make their lips drier.

4. Malnutrition: Lack of nutrients such as vitamin B and iron may also lead to dry lips.

5. Allergic reaction: Some lipsticks, toothpaste or food may cause allergic reactions in children, resulting in dry lips.

6. Diseases: Some diseases such as oral ulcers and psoriasis may also cause dry lips.

If the child's lips are often chapped, parents are advised to take their children to see a doctor to determine the specific reasons and take corresponding treatment measures. At the same time, parents can also give their children plenty of water, keep indoor humidity, and avoid excessive licking of lips to alleviate the problem of dry lips.
