How to add baby/child model to my mob?

For now this is not possible, you could make another mob for children type, though.

It is possible, im trying to do atm, you need to change the code somehow, here is how i use to do on Mcreator 1.8 (for Minecraft 1.12)

public void serverLoad(FMLServerStartingEvent event) {
	}

	@SideOnly(Side.CLIENT)
	public void registerRenderers() {
		RenderLiving customRender = new RenderLiving<EntityAgeable>(Minecraft.getMinecraft().getRenderManager(), new ModelBlackCaiman(), 0) {

			protected ResourceLocation getEntityTexture(EntityAgeable par1Entity) {
				return new ResourceLocation("Crocodile_BlackCaiman.png");
			}

			protected void preRenderCallback(EntityAgeable entitylivingbaseIn, float partialTickTime) {
          float f = 1.4F;
          if (entitylivingbaseIn.getGrowingAge() < 0) {
               f = (float)((double)f * 0.5D);
               this.shadowSize = 0.35F;
          } else {
               this.shadowSize = 0.7F;
          }
          GlStateManager.scale(f, f, f);
     } 
			
		};
		RenderingRegistry.registerEntityRenderingHandler(EntitycrocodileBlackCaiman.class, customRender);
	}

if someone know how to do it please post here
