Kristen, who has just released a lifestyle book called Balancing In Heels, shares three-year-old Camden, Jaxon, 22-months, and four-month-old Saylor with her husband-of-three years.

She opened up to Diana in an exclusive chat where she praised the Chicago Bears quarterback for his parenthood help yet insisted the tiredness does effect them both.

The reality star-turned-author, who recently admitted she and Jay were in therapy, said: 'It's hard when you're both tired, as the day goes on, you're racking up all the time you’ve spent doing things.

'We get in those stupid fights all the time… Jay is so great. He was my night nurse for a few night…I am very lucky to have him, I cant do it without him.'

When Diana asked her if any more children were on the cards, the beautiful star said: 'No, I am pretty sure I am done.'

The parenthood vow comes just days after Kristin hinted that Jay would be undergoing a vasectomy, when she said they were taking 'permanent measures' for birth control. 

While Kristen is evidently totally enamoured with her brood, she did reveal the hardships of parenthood: 'There's no downtime, no time for yourself, you're tired... Being a mom is a tough job.'

Outspoken Kristen also addressed the stunned reaction when she revealed she makes her own formula or feeds her children goats milk - in an unconventional feeding method. 

No more kids: When Diana asked her if any more children were on the cards, the beautiful star said: 'No, I am pretty sure I am done'

The star, who caused shock when she shared a snap while breast-feeding last week, was fiercely defensive of the method of which she included the recipe in her book. 

She told Diana: 'So what we did, when I was done breastfeeding my babies, I would switch it up with homemade almond milk or homemade goat milk formula that we made with our pediatrician.

'Goat milk is very popular in Europe and other parts of the word… Both of my boys have cows milk sensitivity…So that’s why we came up with this formula, I really believe in it... I love it for my children.'

The defiant star insisted she is not preaching but merely sharing: 'I have never once told anyone else what to do with their kids or to give them this formula, my book is about what I do and how to live my life. I am not here to tell anyone else what to do, but it works for us.' 

Feeding time! The star, who caused shock when she shared a snap while breast-feeding last week, was fiercely defensive of the method of which she included the recipe in her book

In therapy... The reality star-turned-author, who recently admitted she and Jay were in therapy, said: 'It's hard when you're both tired, as the day goes on, you're racking up all the time you’ve spent doing things' 

She also discussed her love of her breast pump - yet again in a nod to her Instagram snap last week. 

Kristin said: 'My breast pump has been my best friend, I have Sailor here with me, its actually been kind of nice... I fed her before I left, she's sleeping now, she's up anyways, its actually worked out well, I've only pumped once or twice…It’s a hard job, I am dedicated.'

In further Hills baby news, Kristin has revealed she has stayed in touch with fellow cast member Audrina Patridge and has been giving her advice throughout her pregnancy. 

She said: 'We've been talking during her whole pregnancy, shes been asking me about maternity jeans….shes really excited I am really happy for her.'
