Baby rockers are safe when used correctly, but parents or guardians need to pay attention to the safety of infants at all times. Here are some safety precautions to take when using baby rockers: 1. Make sure your baby's head and body are supported and don't slide out of or tip out of the rocking chair. 2. Don't place the baby high in case of accidental falling. 3. Don't leave the baby in a rocking chair for long time to prevent accidental injury to the baby. 4. Don't place the baby in a rocking chair that shakes too hard to prevent injury to the baby. 5. Regularly check the structure and safety performance of the rocking chair to ensure that there are no damaged or loose parts of the rocking chair. In short, the use of baby rockers requires constant vigilance to ensure the safety of infants. If you have any concerns or questions, it is recommended to consult a professional doctor or pediatric nurse.
