RoRo is building upon its signature Lulla Doll, succeeding the original with a new product collection. The original “miracle sleep doll” offered soothing sounds to help calm kids to sleep.

Coral, Sky, and Lilac are the versatile collection of new dolls for babies of any gender or race. The new dolls feature extended playback time, softer and more durable material, and a weighted base for the added capability of sitting upright for play and shelving.

Lulla Doll was created as a sleep aid to comfort caregivers and kids when they cannot be together. The doll plays a recording of a human heartbeat and breathing, and is designed to “transfer the scent of the caregiver into its fabric” to mimic co-sleeping and human contact.

The enhanced sound technology in the new dolls is powered by two AA batteries for up to 12 hours of sound with adjustable volume. The body is durable and machine washable.

The new doll assortment is expected to begin shipping in April.
