The Formula One heiress, 30, opened up about her Kensington Palace Gardens house, her five-month-old daughter and married life while interviewing for a spread in the Times Magazine Interiors.
"It's rare for these houses to come on the market," Ecclestone said of her 70-million-pound ($117 million) home. "The minute I walked in, I knew it would be a wonderful family home. It had a great energy. I felt it could be a home for life."
The television personality has been living in the four-story abode with her husband Jay Rutland and their five-month-old daughter Sophia for one year.
"We seem to live in three rooms at most: the kitchen, where I make breakfast -- that's my forte; the sitting room, to relax and watch TV; and our bedroom where Sophia also has her cot," added the socialite.
On the subject of her new bundle of joy, Ecclestone confessed she wasn't planning to breastfeed her baby for any longer than two months.
"My sister breastfed for 14 months and I said, 'No way, Petra, they have teeth!'" she explained, adding that, "Now I want to breast-feed her forever."
She's had no formula and if I have to give her a bottle of milk that I pumped and I can't do it myself I have an emotional breakdown. I'm that mum stuck in traffic coming home from work and ringing my nanny begging her not to feed Sophia so I can do it when I get home.
As for her husband, Rutland, Ecclestone said he is her best friend and has a good relationship with her father, Formula One chief Bernie Ecclestone, which is "important" to her.
"He has his opinions and tells me if I'm wrong or stupid. I get an honest answer," Ecclestone shared. "He's a great dad and a good husband and my best friend. He works in property, finding it, renovating and selling it on."
