Baby walkers: Are they safe? – Mayo Clinic

Don’t allow your baby to use a baby walker and make sure that your baby’s other caregivers don’t use baby walkers, either. Instead, consider using a stationary walker or activity center. Rather than wheels, these devices have seats that rotate and bounce. They will allow your baby to play safely as he or she learns to walk.
