Is the bone protrusion under the baby's neck at 1.5 years old gynecomastia?

Patient's question:

No

Doctor's answer:

Hello, according to your description, this situation does not rule out the possibility of calcium deficiency. It is recommended to supplement with fish oil regularly to help with calcium absorption and prevent/treat conditions such as rickets in babies, X-shaped legs, pigeon chest, square skulls, and beaded ribs.
