Baby Halloween costumes are made for cuddles and photos: cosy all-in-one pumpkin suits, little bats, skeletons and animal onesies in soft, gentle fabrics. Pick a design with poppers down the legs for easy nappy changes and no scratchy labels, and one that layers over a babygro if the evening turns cold. They pair with our toddlers' Halloween costumes and the wider Halloween costumes range so the whole family can match, and the rest of our Halloween party supplies finish the day. Go by weight and age rather than a set size, as baby outfits vary between makers.
