The Follow-Up: Sleep Training Evidence

Sleep training is one of the most emotionally charged parenting topics online, and this conversation pulls it back to what actually matters, evidence. We talk about how social media amplifies fear and confusion, why parents are told to “trust” personalities instead of data, and how looking directly at research helps cut through the noise. While opinions are loud, the body of evidence around behavioral sleep interventions is far less controversial than the internet suggests.

We also walk through what the data says about timing, safety, and developmental readiness. From common myths about brain development to the fear of letting a baby cry, this episode centers on nuance. Sleep training is not all-or-nothing, not one rigid method, and not a replacement for parenting. It is a flexible set of tools families can adapt based on temperament, comfort, and goals.

• Why social media creates confusion around sleep training
