No. SNOO is designed to give babies a mix of movement + white noise, just as your baby enjoyed in the womb. For thousands of years, mothers have noted that simultaneous rocking and shushing work best to lull babies into slumber. In fact, white noise is so beneficial for sleep. Dr. Karp recommends parents continue using it long after their child has outgrown SNOO (to at least 1-year of age...or many years more!).
