World Book Day is on Thursday the 6th March 2025. It’s a fun celebration of literature that fosters imagination and creativity in our kids. My children’s school encourages them to dress up as a character from one of their favourite books and I’m pretty sure the the rest of country has a similar celebration.
I like this day because it seems to encourage my kids to read, and it gives them a chance to do something fun at school and get dressed up.
Having kids who are different ages has shown me that finding a World Book Day costume for a toddler is the hardest costume to find. Older kids often have a clear idea of what their favourite book or series of books are. Toddlers in nursery or even kids in foundation stage either have a favourite books or have no clue what to pick.
As the owner of a four-year-old, we’ve reverse engineered her wanting to turn up as a unicorn to match it with a book she likes about unicorns but I know other toddler-parents won’t be so lucky. So with that in mind, I thought I’d share the list of possibilities that we went through before settling on the final costume.

- Hand-me-downs or second-hand shops: Check thrift stores or ask friends for old costumes.
Sometimes the perfect costume starts with the perfect book. If you’re planning ahead and want to grab a few storybooks to inspire your toddler’s costume (or just grow their library), check out AbeBooks coupon codes for discounts on new and used children’s books. It’s a great way to stock up without spending a fortune—especially if your little one falls in love with a new character every week!

Comfortable and Practical Costumes
Since toddlers are always on the move, comfort is key. Keep these things in mind:
- Use soft and breathable fabrics to avoid irritation.
- Avoid heavy or elaborate accessories that might be uncomfortable.
- Choose outfits that are easy to put on and take off (especially for diaper changes or potty breaks).
- Make sure shoes are comfortable if they’ll be walking around a lot.
