Your child should choose the moment when it wants to stop sleeping in the NONOMO®. Your child will let you know. The NONOMO® Toddler can be used up to the age of preschool, if your child prefers sleeping in the hammock. But we do not know of any children who didn't want to sleep somewhere else than in the NONOMO® up to this age. Please pay attention to the safety instructions for safe sleeping in our NONOMO®.
