When to Start Sleep Training? What Scientific Studies Reveal

Effectiveness-wise, based on two reviewed studies, sleeping training can start as early as in the first month. One study indicates that after 3 weeks of training, 72% of babies can sleep more than 5 hours without crying at 12 weeks of age.

People may think that this kind of training could affect the child's emotional well-being, but based on 1 reviewed longitudinal study, sleeping training during infancy has no long-term negative influences on children’s mental health, behavior problems, or parent-child bonding.
