Halloween costume ideas

Halloween is a great excuse to have some fun with fancy dress

Halloween is a chance to make your adorable little ones look even cuter with fancy dress.

Even though it’s supposed to be a scary time of year, there’s something about a baby in a skeleton onesie that’s anything but spooky.

Even if you’re not going trick or treating with your little ones, many baby and toddler groups or local play centres hold themed events to mark the occasion.

There are already some seriously spooky outfits on the high street.

I know from past experience that buying the costume the week before is a bad idea, as you can guarantee the size you need will be out of stock.

Your child might want to be a monster, a bat, a pirate, a witch or a unicorn. Whatever their favourite is, let their imagination run wild this Halloween, there are loads of costumes to choose from!

So here are some ideas from my favourite shops to give you a head start. Head on over to my Pinterest profile for more Halloween costume inspiration and playtime ideas to make this the creepiest fright night ever.

As with all things involving children, do remember to be safe.

There have been warnings about the safety of Halloween costumes in recent years so try to double check you’re making the safest purchase for your child. Here’s a post on Halloween costume safety with lots of helpful advice on picking out an outfit.

If you are planning to carve pumpkins and decorate the house, try switching real candles for LED candles. No one can tell the difference if you buy flickering ones and they’re tucked inside a lantern or pumpkin.

Have a fabulous Halloween!
