The child and eight other people were killed in the central city of Homs while seven people died in the town of Maaret al-Naaman, near the western city of Idlib, the activists said.
Two people were killed in the region of Daraa, epicentre of protests that have gripped Syria since March 15, one died in Daraya, a suburb of Damascus, and one in the coastal town of Latakia, they said.
Protests were also reported in several other towns across the country.
A militant said a demonstration was held outside a mosque in central Damascus but it was quickly dispersed by the security forces.
Another activist in Homs reported that security services stormed a local hospital and removed several wounded along with the body of a victim.
In Ain Arab, a mainly Kurdish region near the northern city of Aleppo, hundreds took to the streets holding olive branches and chanting, "No to violence, yes to dialogue" and "We are not Islamists or Salafists, we want freedom," said Radif Mustapha, head of a Kurdish rights group reached by telephone.
"No one is calling for the downfall of the regime," he said, as the demonstrators could be overheard shouting "azadi, azadi," or freedom in Kurdish.
In Banias, thousands of men, women and children marched, with many of the men bare-chested to show proof they were unarmed, Rami Abdel Rahman, of the London-based Syrian Observatory for Human Rights, told AFP.
The accounts could not be independently verified as foreign journalists are prevented from travelling in the country to report on the protests that have posed the greatest challenge to the authoritarian regime of President Bashar al-Assad.
Crucially, both Damascus and Aleppo have so far been largely spared the unrest and it is widely believed that should massive demonstrations begin there that would mark a serious setback for the regime.
In a keynote speech on Thursday on the Middle East, US President Barack Obama urged Assad to lead a political transition or "get out."
Damascus, however, defiantly rejected the warning, countering that Obama`s appeal was not aimed at easing tensions in Syria but rather at sowing discord.
More than 850 people have been killed and thousands arrested since the protests began in mid-March, according to human rights groups and the United Nations.
Assad`s government has blamed the violence on "armed terrorist gangs" backed by Islamists and foreign agitators. (*)
