Hello,
These appear to be common newborn skin variants, often caused by dilated superficial blood vessels. In most cases, they are harmless and tend to fade gradually as the child grows.
There is usually no need for any treatment. However, you should consult your paediatrician if the mark increases in size, becomes raised like a bump, changes in colour.
You can also discuss this with your paediatrician during the next vaccination visit, as a direct examination will help confirm the diagnosis and provide reassurance.
