The toddler also won first place in a local costume contest, according to his mom.

\"This year will be his first time actually trick-or-treating, and I wanted something unique and original for him to wear,\" Thomas told Storyful. \"So we decided on Big Bird, which took a few days for me to make.\"

Fellow parents were amazed that she got her son to wear his full Big Bird costume, including the head piece. Thomas revealed she had a plan for that, too.

\"The only way I could get him to leave the hat on was by telling him that he would go outside, but he had to wear a hat,\" she said. \"We live in Montana and we’ve already had cold weather, so he understands needing a hat to go outside.”
