Mrs Melling said she took her children out of school during term due to the “unbelievable price” of holidays in the summer months.
One travel agent told the BBC that holiday costs can be as much as 40% higher during the school holidays.
“It was £5,500 to go in the summer and to go in February it was £2,500, it’s a no brainer,” Mrs Melling said.
“We know primary school age is important, but they’re just babies compared to GCSE age.
“They should be living life and experiencing different places around the world if they have that opportunity.
“I could understand if I was taking my children away every single year, but if it’s a one-off, I don’t see why I should get fined.”
She added: “I’ve been made to feel like I’ve done something wrong, but I was treating my children and giving them a good life in my eyes.
“Since my TikTok, I’ve had a lot of support from parents. Everybody has been saying how they’ve always taken their kids out of school and their children are now lawyers, it’s done them no harm.”
