Hello, I'm an expert in dermatology with a focus on pediatric skin conditions. When it comes to birthmarks, it's important to understand that they are not typically growing in the sense that they expand beyond their original size as a baby grows. However, as a child grows, some birthmarks may appear to become larger due to the increase in the size of the child's body.

Birthmarks are developmental and are present at birth or appear shortly after. They can be flat or raised, and they come in various colors, such as pink, red, brown, or blue. Some birthmarks, like strawberry hemangiomas, may even change in appearance over time, often becoming less noticeable as the child grows older.
