Baby Halloween costume ideas: Adorable outfits from ASDA, Amazon and more

Ellie Davis

Halloween is just days away, with plenty of treats around the corner.

First celebrations are always important, from birthdays to Christmas to the fun of October 31's ghoulish holiday. We know you want to make every occasion as memorable as possible, with pictures to cherish and, possibly, bring out at every major moment in their life – or at least make you and your friends chuckle on Instagram.

To make life easier, choose a costume that can be taken on and off with ease for those inevitable nappy changes. It's also worth remembering that temperatures could drop at the end of the month, so added insulation during trick or treating won’t go amiss.

From classic costumes to new and adorable ideas, we've rounded up the best pint-sized fancy dress outfits for your favourite little monsters – with cute factor guaranteed.
