Mindy Kaling's daughter ''knew'' not to cry when she visited Oprah Winfrey.

The 'Ocean's 8' star gave birth to her daughter Katherine five months ago, and has revealed that during a visit to Oprah's house earlier this year for a screening of their recent movie 'A Wrinkle In Time' - which also starred Reese Witherspoon - the tot didn't make a sound, despite having been ''really fussy'' on the journey to the showbiz superstar's home.

Mindy revealed: ''I was scared because I had to bring my baby with me because she was so little at the time, and she'd been really fussy the whole way. And I was like, 'Oh my God, am I gonna be the person that brings a screaming baby into Oprah's cathedral of beauty and art?'

''The minute we went in, I was like, 'Katherine, please, please. You have no idea how high the stakes are right now.' And we walked into the door, and her eyes went wide and she stopped crying, like she knew she was in Oprah's house. And then she was just coyly smiling and being adorable for the next four hours.''

The 38-year-old actress is loving her new life as a mother, but admits she had no interest in children before having one herself.

She added: ''I was always the person who, when I saw a one-year-old baby ... I'd be like, 'Hello, young man.' Shaking hands with an infant.''

Mindy's motherhood journey has been relatively plain sailing so far, but the 'Mindy Project' star admits she hasn't quite managed to get back on her pre-pregnancy diet just yet.

Speaking during an appearance on 'The Ellen Degeneres Show', she said: ''When I was really pregnant - when I came to see you last - I was just eating whatever I wanted. Because when you're pregnant you can just say it's cravings, like, 'I needed to have 11 cupcakes because of my pregnancy cravings.'

''But I haven't altered that that much since having the kid. It's not normal to be not pregnant and have a birthday cake on Tuesday afternoon when it's not your birthday.''
