The increased subsidy, up from Bt400 to Bt600 per child per month, will take effect retroactively from January 1 this year.
“The number of children covered for each family will also rise from two to three per family,” Government Spokesman Lt-General Sansern Kaewkamnerd said on Monday.
The SSO has provided child-support subsidies for children up to six years old to parents who are social-security-fund members.
Sansern said the government believed the increased payments would help shore up the birth rate in Thailand.
