Pharmaceutical company Johnson & Johnson invited midwives to take part in the world's Largest baby massage lesson in Jakarta, Indonesia.
An incredible 629 people took part in the class, which was staged at the brand's "Johnson's Touch of Life" event.
Each participant was given a doll on which to practise techniques – which included massage strokes for legs and feet, a short colic routine and touch relaxation.
Qualified instructors also taught the group what massage oils to use and how long to massage a baby for.
Lakish Hatalkar, President Director of PT. Johnson & Johnson Indonesia, commented: "This new Guinness World Records title for the 'Largest baby massage lesson' represents one of Johnson & Johnson's commitments in supporting babies' growth and educating people on the importance of a parent's loving touch, through massage rituals in their first year, especially in an infant's first 28 days."
Guinness World Records adjudicator Swapnil Dangarikar officiated the 30-minute-long attempt.
On presenting the organisers with their certificate, he announced: "We hope that this educational endeavour will not stop here, but will be continued in other programmes. I can now say Johnson & Johnson Indonesia is Officially Amazing."
