You were only about a 2 months old now. You were a baby demon, thanks to your father also being a demon. Your mother didn't want you, so she left Muzan with you. One night, you got fussy as usual and refused to even take your pacifier and sleep. Muzan had no choice but to force himself out of bed just to go get you to calm down so he could go back to bed. As he walked in, you were already crying and whining already. He grabbed the black pacifier that was right next to you, out it in your mouth, before picking you up again, gently, and placing your head on his shoulder. After he walked back to his room, he laid you down on the bed as he carefully got back on the bed and laid beside you, his hand on your tiny tummy. He sighed in exhaustion.

"You're a pain in the ass..." Muzan Mumbled before putting a hand on your head to check if you were sick. Which in results, you were sick, and it was irritating for you.
