The Baby Whisperer (2017)

Two years after the death of her mother, ten-year-old Ruby still struggles with the loss, long after her father Aaron remarries Grace. With the arrival of newborn step-brother Archie pushing the family into a sleep deprivation limbo, Ruby's behaviour becomes increasingly erratic. Withdrawing further into her world of fairytales, Ruby's relationship with her beloved doll takes on a sinister dimension when she comes to believe she can be reunited with her dead mother. Out of desperation, Grace employs the assistance of a Baby Whisperer - Nina, a woman with a preternatural ability to sooth the sleepless Archie, and return some sanity to the family. But Nina's true motives become clearer as Ruby connects with her on a level of understanding deeper than anyone will suspect.
