The dim, theatrical halls of Shadow Milk Cookie's abode hummed with a new, unexpected energy. Not the usual unsettling whispers or the thrum of his own dark magic, but the distinct, high-pitched wails of a baby. A baby forged from his very essence, a challenge he had, with a sly, confident smirk, accepted.

"Honestly, who knew cookie dough could be so… uncooperative when miniaturized?" Shadow Milk Cookie muttered, his multi-hued eyes narrowing as he gingerly – almost comically – attempted to secure a fresh diaper onto his tiny offspring. His normally sharp, changing teeth were momentarily fixed in a grimace of concentration. "This is far more complex than summoning a void beast, darling."

Nearby, Candy Apple Cookie clapped her hands, her scarlet eyes gleaming with pure delight. "Oh, let me! Let me! They're so small and squishy! Like a little candy tart!" She bounced on the balls of her platform Mary Janes, her devilish wings fluttering with excitement. "I can teach them all about fun! We can play dress-up! And make mischief!" Her single fang glinted as she offered a wide, cat-like smile. "I'm going to be the best big sister ever!"

Black Sapphire Cookie, however, kept a watchful, almost wary distance. His lone visible eye, a deep black with a lavender slit, scanned the scene, particularly whenever the small bundle gesticulated wildly. "Just keep the little... creation... away from my studio," he intoned, his voice a smooth, deep baritone that usually captivated audiences but now held a clear note of warning. He clutched his ornate, sentient microphone, its eye-like head peering intently at the baby. "And absolutely, positively, do not let them touch the microphone. It has a very particular temperament." He adjusted his crisp white cravat, a slight shudder running through his stylish form. "It's not a toy."

Shadow Milk Cookie merely chuckled, a low, unsettling sound. "Relax, Sapphire. What's the worst a mere babe could do?" He finally managed to secure the diaper, letting out a small sigh of relief. "Entertaining, feeding, nightly routines… it's all part of the grand performance, isn't it?" His hidden ghostly eyes in his hair seemed to shift, betraying a flicker of apprehension he wouldn't admit.

Weeks turned into a flurry of unexpected domesticity. Shadow Milk learned the subtle art of warming milk, the precise rhythm for a lullaby that actually worked, and the true meaning of sleep deprivation. Candy Apple was an enthusiastic, if sometimes overzealous, playmate, often leaving behind a trail of glitter and tiny, harmless pranks. Black Sapphire remained vigilant, his microphone occasionally letting out a low growl whenever the baby was too close, but even he found himself occasionally cooing at the tiny cookie's toothless grin.

Then came the three-month mark. It was late, the manor quiet save for the soft patter of rain outside. The baby, nestled in their crib, began to stir, a tiny whimper turning into a full-blown, ear-splitting shriek. Shadow Milk, groggy and disoriented, stumbled towards the crib.

"What's wrong, my little shadow?" he mumbled, reaching out.

But as his hand drew near, the air in the room suddenly rippled. The usually stable shadows began to writhe, stretching and twisting like dark smoke. The baby's cries intensified, and a faint, eerie glow emanated from their tiny form. Picture frames on the wall rattled violently, then exploded into shards of glass. A vase of wilting flowers shattered, scattering petals across the floor. The spectral eyes hidden in Shadow Milk's hair widened in alarm. As Shadow Milk tried to calm you down which Candy Apple and Black Sapphire ducked for cover…who knew a baby with his magic would be powerfully strong…
