Why do some babies develop teeth earlier than others?

Teething is a process that typically begins between 6 and 12 months of age, but there is a wide range of normal variation. While some babies may begin teething as early as 4 months, others may not start until they are 18 months old or older. There are several factors that can affect the age at which a baby develops teeth, including:

- Genetics: There seems to be a genetic component to teething, with some families having a history of early teething.

- Nutrition: A diet that is rich in calcium and vitamin D may help to promote early teething.

- Prematurity: Premature babies are more likely to develop teeth earlier than full-term babies.

- Medical conditions: Certain medical conditions, such as hypothyroidism, can delay teething.

Early teething is not necessarily a cause for concern, and it does not appear to have any negative consequences for a child's health or development. However, it is important to be aware of the possibility of early teething so that you can be prepared for it and help your baby through the process.
