Mom hopes son's fantastic wheelchair costumes will raise awareness of spina bifida

If you think being in a wheelchair makes it difficult to come up with an awesome Halloween costume, then you definitely haven't met 10-year-old Caleb McLelland.

Caleb was diagnosed with spina bifida and hydrocephalus while he was still in the womb and has to use a walker or wheelchair to get around because of his condition.

When Halloween season comes around each year, Caleb's mom Cassie McLelland creates inventive and amazing costumes by incorporating Caleb's wheelchair.

Whether it be Caleb dressed as Batman driving his Batmobile or Mario riding along in his go-kart, no character or concept is too difficult for Cassie and Caleb's creative minds. Cassie's designs became immensely popular online last year, and with October being Spina Bifida Awareness Month, her costumes have generated more awareness about the condition.

Cassie says the attention was surreal and unexpected, especially when she found out she wasn't the only mom to make elaborate wheelchair costumes.

"I was not prepared for that at all but we had so much fun with it," Cassie told ABC via email. "All the attention never really made sense to me because I'm not the only mom that makes wheelchair costumes...and I'm certainly not the best but we just went with the flow and enjoyed every minute."

"I know the focus was on Caleb's costumes but I wanted to take advantage of this once in a lifetime chance to share spina bifida with the world, it was an honor and a privilege."

While the task of making elaborate costumes like Caleb's seems daunting, Cassie encourages parents to just go for it.

"You can do it. Keep it simple," Cassie said. "I think anyone can make the costumes I make."

Cassie also sells her designs on her Etsy shop for parents who may not be able to make wheelchair costumes for their children. She also has powerful words for parents and children who are facing spina bifida.

"It's going to be okay. That sounds so simplified, I know. It really is going to be okay though," Cassie said. "I remember the paralyzing fear when I found out that Caleb had spina bifida. I was 18 weeks pregnant and terrified."

"But then I blinked and Caleb is 10 years old now. If I had only known how amazing he would be, how funny and smart, how handsome and active, I wouldn't have been so scared. So yes, it's going to be okay."

Cassie said that she already has an idea for Caleb's costume this year, although her favorite will always be when her son dressed up as Mario driving his go-kart. You can follow Cassie and Caleb's adventures and meet other children with spina bifida at the McLelland family blog.
