I really like the idea of Satan being born like a literary a baby but growing fast like Renesmee from twilight.
Mammon: "Lucifer!! I lost the thing!!"
Very exhausted Lucifer: "that thing, is above you".
Que toddler Satan hanging off the ceiling like a cat .
Asmo: "does this mean we gotta go clothing shopping again this week?"
Lucifer trying to pull Satan down, que screaming, growing, feral child.
"Lucifer, he is growing again".
"Am very VERY much aware Belphine".
"Not everyone is hungry every 30 minutes Beel".
"Uhhh, Lucifer do you need help?"
Lucifer being attacked and bitten for the ninth time, again.
"Yeahhh, why don't we take Satan for a bit while you sleep?".
Lucifer literally throwing his brothers out of his room being he is never going to waste an opportunity to get away from his feral son.
"Maybe we should ask Diavolo for extended maternity leave....".
