Baby Halloween costumes are definitely one of the cutest parts of parenting and we've found some amazing ideas to pull off a winning look. 

While you might think Halloween costumes for kids need to be classically spooky - bats and devils etc - and they certainly can be, you can also update the Halloween guidebook and go for outfits based on your favourite Halloween movies for kids and adults or even food and drink items. As well as keeping the little ones warm if you're out trick-or-treating, these costumes are comfortable and snug.

Suitable for ages up to 24 months, these are the best baby Halloween costumes we've found to buy online this year.
