The Ted beauty gave birth to the couple's first child, Wyatt, in October (14) and the stars have made an extra effort to keep their relationship in check by taking time to themselves on a weekly basis.

Kunis admits banning all baby talk on nights out has been tough, but they are determined not to let parenting duties consume their lives.

She says, "Somebody gave us that advice when I first got pregnant: 'Make sure to take time for yourselves', and so we have my parents - we're very lucky, they live down the street - so we have them do what's called monitor sitting, 'cause the baby goes down to sleep and they have to watch the monitor, and I would say once a week we go out on a date.

"If not just the two of us, we'll go out on a double date or something, just to reconnect, and we make an effort to not talk about the baby. It's hard. You catch yourself though... but it's important... For that one hour, we try very hard to connect..."

However, Kunis confesses the baby is always on her mind - even during sex.

She tells new U.S. talk show host James Corden, "I've thought about it (the baby during sex)... like, 'I wonder if that's her making that noise...'"

And the actress, who played coy during the interview over reports suggesting she and Kutcher are secretly married, reveals she is already thinking about baby number two, gushing about her beau, "He's an amazing father."
