“The first two teeth are gone,” Hannigan, 40, told PEOPLE of daughter, Satyana Marie, 5½, at Thursday’s Disney on Ice presents Let’s Celebrate! in Los Angeles.
“The first one … she pulled it out herself. It was dangling there. I said, ‘Get the camera!’ And we got it on video.”
Just two weeks later, a second tooth was ready to come out, but this time, the actress stepped in to offer a helping hand.
“She was getting frustrated. She kept saying, ‘You do it.’ So I was wiggling it and then I pulled it,” shares Hannigan. “She gave me this look like, ‘See? You can’t do it either!’ And I showed it to her in my hand. She was blown away.”
