After Coraline leaves the kitchen, she see's her father 'playing' piano (He seems a little off, but he hides it because of the beldam) He plays her a song:
Making up a song about Coraline! she's a peach, She's a doll, she's a pal of mine! She's as cute as button in the eyes of anyone who laid their eyes on Coraline! When she goes around exploring, Mom and I will never ever make it boring, our eyes on Coraline!
Some people say the other father is giving her hints,
"She's a peach" (The other mother will try to eat her) "She's a doll" (The other will try to control her)
"She's as cute as a button" (The other mother will try to sew buttons into her eyes),
"Our eyes will be on Coraline" (The beldam will be watching her),
"Mom and I will never ever make it boring" (They will make her life better than her life with her real parents)
But these questions were never answered.
