Book Week is Sneaking Up on Us Again – Here’s How to Beat the Scramble!

 

 

If Book Week has a way of creeping up on your every single year, no matter how much warning you’ve had, this one’s for you! New research from Big W found that 49% of Aussie parents leave costume planning until the last few days. (No surprises there!)

But it’s not just the planning that’s the issue. Almost nine in ten parents have hit some kind of costume hurdle, nearly one in five have had a kid completely change their mind on them at the eleventh hour the night before.

The good news is BIG W has just rolled out Same Day Delivery with DoorDash.  Order before 12pm in an eligible postcode and it’ll be at your door that afternoon!

Mum of two and content creator Nat Alise knows this scramble better than most. She says Book Week always manages to surprise her — one year it’s under control, the next she’d got one kid switching characters overnight and another suddenly deciding they need something completely different. Being able to order online and have it turn up the same day, she says, takes the chaos out of it and let’s her family actually enjoy the fun part.

Jolene enjoys writing, sharing and connecting with other like-minded women online – it also gives her the perfect excuse to ignore Mount-Washmore until it threatens to bury her family in an avalanche of Skylander T-shirts and Frozen Pyjama pants. (No one ever knows where the matching top is!) Likes: Reading, cooking, sketching, dancing (preferably with a Sav Blanc in one hand), social media, and sitting down on a toilet seat that one of her children hasn’t dripped, splashed or sprayed on. Dislikes: Writing pretentious crap about herself in online bio’s and refereeing arguments amongst her offspring.
