Authorities say Patricia Krentcil’s daughter, now six, turned up at her elementary school in Nutley, New Jersey, with sunburn, prompting a school nurse to contact police.
New Jersey is among several states that have adopted regulations prohibiting anyone age 14 or under from using ultraviolet devices because of the risk of skin cancer.
Ms Krentcil, 44, who has extremely tanned skin herself, denied bringing her fair-skinned daughter into the tanning booth of a salon that she frequents.
“I tan, she doesn’t tan. It’s called a tanning booth and a tanning room,” said Krentcil, saying her daughter was in the room but not the booth.
“I’m not gonna bring my little daughter into a 90 degree bed. I mean, that’s not normal,” she said.
Mrs Krentcil has pleaded not guilty to the charge.
