The former reality star is mom to 5-month-old son, Sullivan
Kate Chastain can’t hold back her excitement about spending her first Halloween with her son.
In the video, posted to her Instagram Story, her baby son was dressed in a multi-colored bird onesie fitted out with wings, a hood and a beak.
"100 percent showing these photos to his first date when he's a teenager," Chastain wrote below the short video as her son's face broke out in a smile.
She added Nelly Furtado's 2000 hit "I'm Like A Bird" as a background song to the post, too.
In mid-October, the former reality star also took to Instagram to show her fans how excited she was to enjoy the start of fall with her son. A video she posted shows Sullivan tucked comfortably in the front of her overalls as she stands outdoors by the docks.
“It dropped below 90 degrees today so obviously we’re out celebrating the start of Fall 🍂🍁,” she captioned the post.
