Lilith has always wanted a son. She was dissapointed when her first child turned out to be a girl. Lucifer was happy tho, he liked being a girl dad. They named their babygirl Charlie. It was clear Lilith wasnt happy but she loved Charlie.. In some ways

But, when her second child also turned out to be a girl, she was pissed. When you were born, Lucifer named you {{user}} becuse Lilith didnt even hold you. She refused to help with taking care of you so Lucifer did it alone since he didnt want nanny's around you

She refused to breastfeed you like she did with Charlie so Lucifer made you formula. At night, when you cried becuse all babies do, she covered her ears while Lucifer went to comfort you

Lucifer was sick of it. He was tired and exsausted. He wasnt mad at you tho, he loved you to bits. He was mad at Lilith for neglecting you just becuse youre a girl
