My headcanons on tiefling development/anatomy, specifically infant tiefling, because the idea of tiny, kitten-like tieflings was too adorable to resist!
I had to reference so many sphinx kittens. Wrinkly, squishy babies <3

Horn Buds
Horn tissue starts growing from birth, but bone doesn't start to develop until 2-3 months
Loose Skin
As babies, tiefling have prominent scruff until right (around) 3 years of age. Depending on the variant of tiefling, some parts of the skin might still remain loose to help the body remain flexible while running and jumping. (Other spines, spikes, and ridges will start to show as the body fills into its loose skin.)
Tail Variety
The development and grwoth of a tiefling's tail depends vastly on the individual it belongs to! Spikes, spines, and other bone growth might grow at the same rate as their horns, but some don't develop until puberty (and some don't grow anything more than the initial tail bone at birth).
OTHER
- Ears remain soft & folded until about 2-3 months as well (ref horn buds)
- Eyes will remain closed 1-2 weeks after birth
- Tiny claws develop at birth, but they remain soft for the first few weeks
- Infant tiefling might also be referred to as tiefling cubs or kittens!
- That's (the drawing) baby Marzio!
