Kunis shared the surprising information in an interview whilst promoting her latest film, Bad Moms 2.
She told Extra: 'We do Shabbat at our house. At Shabbat, you have a sip of wine. My daughter has had a sip of wine since she was born… Friday mornings she wakes up and I say it’s Friday, she says, ‘Oh, I can have wine!’'
For those confused what Shabbat is, it's a Jewish celebration and a day of rest which begins on Friday at sunset and ends on the following evening.
The Bad Moms star who married Ashton Kutcher in 2015 share two kids together, both Wyatt and son, Dimitri are both very private when it comes to their children.
Both Kunis and Kutcher do not share any photos of their family on social media and keep them away from the public eye.
