Paetongtarn gave birth to her second child Prutthasin “Thasin” Sooksawas on Monday and the occasion was announced on social media.
On Wednesday morning, the press gathered at the Praram 9 Hospital in Bangkok’s Huai Khwang district to catch sight of baby Prutthasin, who was carted out in an incubator for a brief photo opportunity with his mother, father, aunt and grandmother.
The baby had been delivered at this hospital.
A frontrunner for the opposition Pheu Thai Party, Paetongtarn has been leading opinion polls as a favourite PM candidate since campaigns began for the May 14 election.
Paetogtarn’s father, former telecommunications tycoon Thaksin Shinawatra, was toppled in a 2006 military coup and his sister Yingluck Shinawatra’s government was ousted by the military in 2014.
Both Thaksin and Yingluck live in self-imposed exile to avoid prison sentences that their allies say were designed to prevent a political comeback.
