Elsie Rose was on her first outing with her parents, Amy Duckers and Lewis Temple, and her seven-year-old sister, Libby.
The family was at the Tesco store in Baguley, Greater Manchester, and were showing her off to friends when it is alleged a man came over and punched Elsie, leaving a “very big fist mark” on the baby’s forehead, according to Ms Duckers.
Elsie, who weighs 6lb 12oz (3kg), was kept overnight in hospital but is not thought to have been seriously injured.
While the “mortified” parents alerted security at the store, the suspect apologised, saying he thought the baby was a doll.
Ms Duckers praised the supermarket staff on her Facebook page for the way they handled the situation.
“Thank you so much to Baguley Tesco for all you did tonight,” she wrote.
“You were all amazing thank you so much for the way you dealt with the situation and treated us all.”
Greater Manchester police confirmed a man had been arrested.
“Police were called shortly before 6.45pm to a supermarket on Altrincham Road in Baguley, 5 September 2016, to reports of a child having been hit,” a spokesman said.
“The baby girl was taken to hospital as a precaution and has since been discharged.
“A 63-year-old was arrested on suspicion of assault and is currently in custody being questioned by officers.”
