Kristen Bell uses sign language to communicate with her daughter.
The ‘Frozen’ star, who is expecting her second child with husband Dax Shepard, thinks their 17-month-old little girl, Lincoln, is "the smartest baby ever" because she is already talking "a bit" and knows "40-50 signs."
She said: "She signs a lot, which is nice. There’s a lot of research to suggest that they will be happier if they can communicate before their verbal scores are developed.
"There’s a time when they can understand everything you’re saying but their verbal scores don’t exist."
She added: "I can talk to her and she’ll sign in three, four word sentences which is really amazing. She’ll come in the kitchen and be like [signing] ‘More crackers please!’ And I’m like, ‘Yes, okay!’ "
She added: "She’s MENSA, without a question!? She’s the smartest baby ever!"
But the 34-year-old actress admits Lincoln is also already very opinionated.
She told UsMagazine.com: "It’s the tantrum stage."
Kristen’s second pregnancy is going smoothly and she is grateful her hormones aren’t out of control.
She said: "Same as the first one! Really easy, thank God. I’ve had a lot of friends who have had rough pregnancies and I’m really, really thankful.
"People are affected differently by hormones, we’re all different."
