World Book Day has become a massive day for pupils - and parents.

But this year many schools in the area are doing things a little differently.

Some parents have been told their child is being asked to wear pyjamas instead of costumes of their favourite book characters when the big day returns tomorrow.

In its 23rd year, World Book Day was created to encourage children to the joy of books and reading. But over the years it has become more about the costumes children wear.

This, critics claim, can put financial pressure on struggling families and lead to bullying.

So, this year, many schools in the region are encouraging children to not wear costumes and focus instead on reading. And to encourage less compeition between children - and parents - some schools are asking kids to come in in their PJs instead.

One Bolton parent, who didn't want to be named, said: "I think it's a shame as every year my child loves dressing up in their favourite costume.

"However I can see the practical side of it, if some parents cannot afford to buy costumes, or have the time to be creative and make one, then it's completely understandable.

"At least all children will be on the same page and no one will feel left out if their costume isn't as extravagant as someone else's."

Another mum in Bolton said: "I love being creative and allowing the kids to dress up.

"But I also think the love of books sometimes can become lost in the fact dressing up can become quite competitive and expensive for some parents.

"This way every child can have a moment to share a good book and stops the added pressure on some parents that struggle.

"I think the school do anything to keep all children equal and happy which I love.

"I think it gives them great opportunities to be on the same level.

"I always hand make things and have always sent pictures to the newspapers but think this is a way to celebrate the story rather than it become a competition or a big money-making thing."
