French President Emmanuel Macron said he has heard "positive" news about the condition of child victims of Thursday's knife attack in Annecy, reports BBC News.
Mr Macron was visiting the town where four children were attacked.
He said a young British girl had "woken up" after surgery. A Dutch toddler is also reportedly recovering.
The suspect - a Syrian man with refugee status in Sweden - remains in custody and is due to undergo a psychiatric assessment.
The 31-year-old is thought to have been living homeless in Annecy and recently had an asylum claim rejected. No terrorist motive is suspected.
Four children in all - aged between 22 and 36 months - and two pensioners were wounded during the assault.
In a speech in the Alpine town, Mr Macron said that attacking children was "the most barbaric act".
He visited a local hospital, where he met a man who was stabbed by the assailant during the attack. He also met Henri, the so-called "backpack hero" who used his backpack to stop the attacker.
Mr Macron said the young British girl who was attacked and received surgery had "woken up".
"She is watching TV and [the attack] is just a bad memory already," he said, according to the AFP news agency.
"Doctors are optimistic," the president said, adding that caution was still required.
Dutch Foreign Minister Wopke Hoekstra said he was "relieved" to hear that the Dutch girl who fell victim to the attack "is out of danger".
