When can I sleep train my baby?

Most methods work from 4–6 months, once babies can self-soothe. Ferber (gradual check-ins), 'chair method' (gradually leave), and 'cry it out' all work; the right one is the one you can follow consistently.

Follow-up questions

Is cry-it-out harmful?

Studies find no long-term harm to attachment or emotional health when done at appropriate age.

Naps too?

Sleep training usually improves naps within 1–2 weeks after night sleep stabilizes.
