For the first time since August, under 16s can be treated at Stafford's County Hospital for minor injuries.
Youngsters have had to be taken to alternative sites, including the Royal Stoke and Wolverhampton's New Cross Hospital, after A&E services for children were suspended over safety concerns.
Since then bosses have been working on ways to provide some services safely, which has included visiting other hospitals to observe their working practices.
Today a Minor Injuries Unit has opened for under 16s at the County Hospital, with 17 and 18-year-olds able to attend adult A&E.
The Unit will be used to treat children with head and limb injuries, wounds, sprains, bruises and fractures.
Those with illnesses, a rash or fever will have to be taken to alternative sites.
Children's A&E services will continue to be suspended until the Royal College of Paediatricians and Child Health has carried out a review, which is scheduled to conclude in January 2017.
