There is no paid tier. - **Is it a real sleep consultant?** It is an AI sleep coach built on medical research, not a human consultant. A private sleep consultant typically costs 100–400 € per program; Lunea is a free alternative and points parents to a professional when needed. - **How is it different from a general-purpose chatbot?** Lunea starts from a full questionnaire about the specific child (age, rhythm, environment, parental convictions) and from the family's tracked sleep data, so guidance is personalized rather than generic. - **Does it require crying-based sleep training?** No. Parents state their convictions, and the plan respects them. Sleep training is never recommended for newborns. - **What ages are covered?** From pregnancy and newborn (0–4 weeks) up to 7 years. ## Optional - [Sitemap](/sitemap.xml): Full list of indexable URLs.
