That miracle, which dates back to February 2014, saw the boy being “fully cured” after he touched Carlo’s relic and said “stop vomiting”, a priest and family friend of Mattheus’s said.
The second miracle saw a girl from Costa Rica who was studying in Italy reportedly being healed after suffering a head trauma.
She was reportedly cured by the boy after he was invoked by her mother, Avvenire, the daily newspaper of the Italian Bishops’ Conference (CEI), reports.
Pope Francis took the decision to attribute the second miracle to Carlo during a meeting with the head of the Vatican’s saint-making department, Cardinal Marcello Semeraro.

The attribution of a second miracle means the boy can now be elevated to sainthood, but the Vatican did not say when this would happen.
The Roman Catholic Church teaches that only God performs miracles, but that saints who are believed to be with God in heaven intercede on behalf of people who pray to them.
Typically, miracles are the medically inexplicable healing of a person.
Due to his “important role in evangelisation through the internet”, Carlo was named as a patron of last year’s World Youth Day in Lisbon, organisers of the event said.
Sir Keir Starmer will join other European leaders in Kyiv on Saturday for talks on the “coalition of the willing”.
The prime minister is attending the event alongside French President Emmanuel Macron, recently-elected German Chancellor Friedrich Merz and Polish Prime Minister Donald Tusk.
It will be the first time the leaders of the four countries will travel to Ukraine at the same time – on board a train to Kyiv – with their meeting hosted by President Volodymyr Zelenskyy.

Military officers from around 30 countries have been involved in drawing up plans for the coalition, which would provide a peacekeeping force in the event of a ceasefire being agreed between Russia and Ukraine.
Ahead of the meeting on Saturday, Sir Keir, Mr Macron, Mr Tusk and Mr Merz released a joint statement voicing support for Ukraine and calling on Russia to agree to a 30-day ceasefire.

“We reiterate our backing for President Trump’s calls for a peace deal and call on Russia to stop obstructing efforts to secure an enduring peace,” they said.
“Alongside the US, we call on Russia to agree a full and unconditional 30-day ceasefire to create the space for talks on a just and lasting peace.”

The leaders said they were “ready to support peace talks as soon as possible”.
But they warned that they would continue to “ratchet up pressure on Russia’s war machine” until Moscow agrees to a lasting ceasefire.
“We are clear the bloodshed must end, Russia must stop its illegal invasion, and Ukraine must be able to prosper as a safe, secure and sovereign nation within its internationally recognised borders for generations to come,” their statement added.
“We will continue to increase our support for Ukraine.”
The European leaders are set to visit the Maidan, a central square in Ukraine’s capital where flags represent those who died in the war.
They are also expected to host a virtual meeting for other leaders in the “coalition of the willing” to update them on progress towards a peacekeeping force.
This force “would help regenerate Ukraine’s armed forces after any peace deal and strengthen confidence in any future peace”, according to Number 10.
Ten explosions have been heard near Srinagar International Airport in India-administered parts of Kashmir, officials have told Reuters news agency.
The blasts followed blackouts caused by multiple projectiles, which were seen in the sky above the city of Jammu earlier on Friday.
Explosions were also heard in the Sikh holy city of Amritsar, in the neighbouring Punjab state, according to Reuters.
An Indian military official told the agency that “drones have been sighted” and “they are being engaged”.
It comes as tensions between Indiaand Pakistanacross the line of control around the region of Kashmirhave boiled over this week, leading to fears of a wider conflict.
On Wednesday morning, Indiacarried out missile strikes in Pakistan and Pakistan-administered parts of the disputed region.
The government in India said it hit nine “terrorist infrastructure” sites, while Pakistan said it was not involved in the April attack and the sites were not militant bases.

Standing on Red Square, this was an intimidating sight, which felt much more like a celebration of war rather than peace.
I could feel the ground shake as the tanks rolled past, their caterpillar tracks on the ancient cobbles providing a deafening clatter.
The hairs on the back of my neck stood up in fear as the phalanxes of troops roared “Hurrah” in response to their commander in chief.
And the sight of combat drones being paraded on their launchers was actually quite sickening. Weapons that have been at the forefront of Russia’s invasion of Ukraine were paraded in a show of pomp and patriotism.

For the rest of Europe, the 80th anniversary of the end of the Second World War has been a celebration of peace, but this felt much more like a celebration of war.
And it wasn’t just military hardware on display here, but the very identity of modern Russia.

For this is a country that is now defined by its military and its memory. The glory and sacrifice of 1945 have been weaponised to give credence to Russia’s current course and to make people believe that victory is their right.
For Russians, it served as a rallying cry and there was applause when the troops who have fought against Ukraine marched past.
But for those watching in Kyiv and other European capitals, it was an overt warning that Moscow has no intention of backing down.

Putin hails sacrifice of Russian troops
The parade was considerably larger in scale than in recent years, when units and hardware have been needed on the battlefield. I think it was a deliberate attempt to project an image of confidence, and so was Vladimir Putin‘s positioning of his guests.
China’s Xi Jinping was given a prime position on the Kremlin leader’s right-hand side. It was no surprise given the economic lifeline Beijing has provided, but it felt like a particularly pointed gesture to the West – that they were looking at a new world order.
Despite that appearance of confidence, there were signs of Moscow’s unease that the parade could be disrupted.
There were snipers on every rooftop. Security was extremely tight. And the mobile internet signal across the city centre was completely shut down for fear of Ukrainian drone attacks, meaning none of the international media that had gathered could broadcast any live transmissions.
After the parade finished, Putin saluted the crowds as they spontaneously erupted into rhythmic shouts of “Rus-si-ya” at the sight of him.
Another PR coup complete without interruption, he will have departed as a very happy man.
