For all intents and purposes Snow is Emma's mother (even if she is not her biologiacal mother, though i think she is), Emma is the product of true love, and her parents Ā and devoted to her, whether or not biological, they have a special connection.
Lily is Mal's baby, imo, Best Laid Plans made that pretty clear. But i'm more interested in the matter of Lily's paternity (provided you don't believe it's charming cause of the switch thing). Is her father someone we know? Or maybe there is no father ... some lizards can reporoduce like that ... and well a dragon is a giant fire-breathing lizard basically.
