This is not a lifesaving device. Do not leave children unattended while in use. Under no circumstances should a child be left in or around water unless a competent adult swimmer is present in the water close to child - supervising child. COMPETENT ADULT SUPERVISION SHOULD ALWAYS BE PROVIDED TO PREVENT DROWNING OR OTHER INJURY. NEVER leave child unattended. Always follow good safety practices. Do not over inflate or use high pressure air to inflate. Not suitable for children under 3 years old. Thank you for your questions.
