The Dreampad has been used safely with infants; however, we do not recommend using it with children under 12 months of age without adult supervision, and only for short periods of time, e.g. less than 30 minutes. Of course, the Dreampad, like all pillow-type products, should not be left in the crib of a child under 12 months of age because of the risk of suffocation. There is no age restriction for seniors using the product.
