"All right," she murmurs, reaching up and resting her fingers against her sister's temples. Breathing in and out evenly, she lets a shimmer of magic flow from her into Riley, reaching out to the sleep inducing part of her brain and tweaking it. "You should be getting sleepy now... That spell will give you a good, dreamless sleep."

Holding her close and half-rocking her, she starts singing quietly under her breath, nothing meaningful, just something soft to lull her to sleep.
