Police said the severely dehydrated children would not have lasted much longer in the cramped vehicle.
The minivan was stopped in Braunau district on Friday and the Romanian driver was arrested after a chase.
A spokesman for local police, David Furtner, said: "The van's driver did not give a damn about the people in the back, and in Austria, even animals are not transported in such conditions."
Separately, four men appeared in court in Hungary following the discovery last week of another truck in Austria containing the bodies of 71 people.
The three Bulgarians and an Afghan, who were arrested in Hungary, were remanded in custody until 29 September. Austria is expected to seek their extradition.
The latest incident - which was not reported until Saturday - happened near the small town of St Peter am Hart, close to the German border.
A police spokesman told the BBC that the children were crammed in the back of the minivan along with the other migrants, said to be from Syria, Afghanistan and Bangladesh.
He said the children - aged about five or six - were critically ill and almost unconscious. Officials said on Saturday that their lives were no longer in danger but they are still in hospital.
Police said they had tried to stop the vehicle and gave chase when it drove off at speed. The migrants said they were hoping to reach Germany.
The discovery of the 71 bodies in the lorry left on a roadside near the Hungarian border last week led to an outcry.
Officials said the 59 men, eight women and four children - thought to be mainly Syrians - had probably died of suffocation two days earlier.
Austrian police were alerted when a road worker saw liquid seeping from the vehicle and the badly decomposing bodies were found inside.

Prosecutors say the four suspects who appeared at court in the city of Kecskemet on Saturday are believed to be low-ranking members of a Bulgarian-Hungarian people-trafficking gang.
So far this month more than 40,000 asylum seekers, the majority of them Syrian, have arrived in Hungary via the Balkans.
Hungary said on Saturday it had completed a 175km razor-wire barrier - aimed at stemming the flow of migrants - along its border with non-EU member Serbia.
It plans to replace the barrier with a 4m-high fence.
Many migrants fall prey to smugglers who wait near the refugee camps, offering to take them at a high price on to western Europe, the BBC reported.
Meanwhile, New Zealand First says the Government should increase the country's refugee quota to help deal with the international humanitarian crisis.
NZ First leader Winston Peters said the current quota that allowed 750 people to be settled annually in New Zealand needed to be reviewed.
He said that would meet New Zealand's international obligations for refugees.
This view was backed by Holocaust Research and Education Centre director Inge Woolf who said these were desperate people, some fleeing war or extreme poverty.
"I feel very much for these refugees, no one gets on these unstable, leaky boats with their families if they aren't desperate. They don't do it for a joy ride."
But she said any increase should be managed to make sure refugees were settled in areas where they were supported and can get jobs.
