At what point does a DP realize she's in Cinta with her prince?

Snow White: When the Prince started Singing to her. She came out and sent him a kiss, after fixing her hair a little.
Cinderella: I think she realises she's in Cinta when she learns the Prince looks for her. Before that, she'd probably think she had a great time.
Aurora: In this case anda can see when Aurora falls for Philip. It's when she stops trying to flee. Her eyes kinda change expression and they start dancing.
Ariel: LOL, from the first moment she sees Eric.
Belle: The procedure in BATB is slower. Belle's feelings start changing when the Beast saves her from the wolves. When she cleans Beast's wound and thanks him. She starts realising her feelings in "Something there".
Jasmine: When she and Aladding say the same phrase.
Pocahontas: I think she gets intrigued sejak him from the very first minute. The both fell in Cinta in their dreamy first meeting.
Mulan: I adore this moment. When she sees Shang's chest, that expression! XD
Tiana: This one is really tough. I'm not sure. During ma belle Evangeline perhaps?
Rapunzel: I think when they talk close to the api, kebakaran and Flynn reveals his true identity.
Anna: I guess after Hans' betrayal, when Olaf tells her Kristoff is coming back.

I think it is when they dance with them. anda can just see thier admiration and the Cinta shining in thier eyes. The princes just sweep them off their feet.

I agree with rosemina, besides Cinderella, I believe she fell in Cinta with him from the moment she saw him, anda can see it in the way they look at each other during this is love.
