Hilary Duff captured a cute video of her newborn daughter hiccuping.
The video shows a closeup of Banks' face as Duff cradles the infant in her lap. Banks hiccups several times before giving a tiny sneeze.
"little bean is a week old today!" Duff captioned the post, adding rainbow, unicorn and star emojis. "she really nails hiccups and sneezes."
The "Younger" star announced Banks' birth in an Instagram post Monday after welcoming the infant Oct. 25.
"This little bit has fully stolen our hearts! She joined our world at home on Thursday afternoon and is absolute magic."
Duff is also parent to 6-year-old Luca Cruz with her ex-husband, retired NHL player Mike Comrie.
"Luca thinks Cofont Croissant is, like, the coolest name," the actress told host James Corden.
"When I refer to it as 'Cofont,' and I'm like, 'That would be so cool, nobody at school's gonna be named Cofont,' and he's like, 'Croissant. Cofont Croissant.' It, like, goes together," she said.
