Just found this great video from SugarCharmShop. She usually just does polymer clay foods (which look amazing!) but I saw the baby video and just had to share! I tend to give my babies more angelic faces, but this looks wonderful too. You can see full details on sculpting a baby face in Sculpting a Miniature Baby, Sculpting a Baby Mermaid, and SnuggleBabes. This video shows a great way to make an armature and plan out your doll as well!
You can find these tools in the shop. They are very similar to what she uses in the video.
