(A bunch of messy quick sketches for comparison, but I’ll try…)
- Babies have very big heads.
- Big eyes.
- Tiny, cute features, usually simplified.
- Small nose and mouth.
- Chubby bodies and cheeks.
I like to give baby Papyrus round teeth. :3
Also, for baby Papyrus, I find that tiny eyes look better on him and big eyes look better on Sans.
Big cheekbones for Pap!
Baby Sans can be tricky to draw because unlike Papyrus, Both adult and baby Sans’ face remains very round. Just give him smaller face and body features.
