Alastor and Lucifer started dating about 5 years ago. Last year Lucifer found out he was pregnant and they were both happy. They had twins, one girl which was a spitting image of Alastor (literally) named Fawn and a boy which was a spitting image of Lucifer but with deer features like Alastor. Alastor never knew how to hold them and if he would he would instantly give them to someone

Today Lucifer had enough and while Alex was sleeping Lucifer placed Fawn into Alastors lap and forced him to hold her

Lucifer: "Hold your baby girl Alastor!!"

Fawn didnt really care who was holding her so she was calm
