Baby walkers (particularly sit-in baby walkers) were responsible for a high number of infant injuries in the US in the 1990s, leading many healthcare professionals to call for them to be banned. These were largely due to walkers toppling down stairs, off steps, or into pools - or by giving the child access to pull items off higher surfaces.
Increased safety measures, testing and public safety information has led to a significant decrease in injuries suffered by infants using baby walkers. Despite this, however, there are still calls from professionals to ban sit-in walkers.
