Having a child with autism always means dealing with specific challenges, but during Halloween, they can be amplified. Autistic children's sensory issues can make things like getting dressed or dealing with noises an obstacle — and by extension, finding sensory-friendly Halloween costumes for kids can be quite the task. The materials are often scratchy, and there are frequently wigs, masks, and makeup that kids with autism have no desire to wear, even if they desperately want to be those characters for Halloween.
There are myriad strategies I've learned while dressing my own autistic son at Halloween. In the first few few years, I thought I had to spend gobs of cash on pricey costumes that were designed specifically with autistic kids in mind. While those costumes were great, and really cute, they were hard on the budget. Now, I've learned that so long as you experiment before the big day, and work with clothing that your children are already comfortable with, you can really put together some fantastic costumes.
Autism is a spectrum. Some children, like my own, are fine with makeup for short periods of time, but will never put on a mask or a wig. Some kids' sensory issues won't even permit makeup. You need to strategize, and try things out long before the big day so that you can gauge what your child can handle. Just like for trick-or-treating itself, your expectations need to fit your reality. I know that my kid has an absolute max number of places he can visit before he has just had it with the whole thing and needs to recharge.
