Family of eight ... Antonia Kidman is pregnant again.

Family of eight ... Antonia Kidman is pregnant again.

Antonia Kidman has confirmed she is pregnant with her sixth child.

The 42-year-old TV personality, author and Essential Kids columnist has confimed she’s six months pregnant to her husband, Craig Marran, and is due in December.

It's something about the hustle and bustle of lots of children that appeals to me. There is rarely a dull moment 

It’s the second child for the couple, who are already parents to 20-month-old son, Nicholas. Kidman is also mum to Lucia, 14, Hamish, 11, James, nine, and Sybella, five, from her previous marriage.

"I don't think there's much difference between five and six (kids), but if you ask me in a few months' time when I've got a screaming newborn and feeding every three hours, I might say differently," she told the Daily Telegraph’s Confidential.  

In the past, she has spoken about the challenges of raising a large family.

"Lately, I've found myself looking at the younger two and recognising that they don't receive the same amount of my undivided attention as perhaps their siblings did at their age," she said.

"However, my concern is short-lived as I rationalise it by reminding myself that what they have is the love and attention of three older siblings who are always happy to read, cuddle and play with them at any opportunity."

But she has always wanted a large family, saying, "It's something about the hustle and bustle of lots of children that appeals to me. There is rarely a dull moment," she said.
