Earlier this week I shared baby Halloween costumes or outfits for girls. And today’s post is all about baby boys and infant boys. I came up with baby Halloween costumes and baby Halloween outfits that are best for boys. These were really fun to find as I was looking for Halloween costume ideas to make for my 8 month old baby boy. I love so many of these ideas, it’s going to be really hard to choose one that I think is perfect for him.

Since, my older son chooses to be spider man. And loves everything superheroes related! I can only make a baby Halloween costume. Especially something which is easy to whip up. Like a no sew Halloween outfit. Or a Halloween onesie would be just something I can make.

The Halloween costumes/ outfits I am sharing today are easy, cute and very affordable. And I love comfortable Halloween costumes for babies.

Because a happy baby is everything!

Let’s get started with the Halloween costume ideas:
