Speaking to Hello! magazine, Kirstie - who is not married to her partner Ben Andersen, says:
'If you do what your partner prefers, he is happy and the children have a great time too.
'Your relationship with your partner will last far longer than your children are going to be at home. If you let that relationship slide when your children are little, it might disintegrate and you might not be able to rescue it. So at the weekend I let Ben choose what we do.'
Kirstie - who has sons Bay, five, and Oscar, two, with Ben, also claimed that ensuring men have enough food and sleep was also paramount to a good relationship:
'If you want to talk about feelings, make sure they have a full stomach when you do it.
'If I want to talk to Ben about something difficult, I shouldn't do it when he walks through the door after work. That is the best way to have a flaming row'.
Kirstie says that being a wife and mum was what she had wanted since she was 16, and as such, she was happy to make sacrifices:
'I have what I want in life. Two adorable children, two great stepchildren, and a partner I adore.'
Hmmm. All sounds a bit 1950s housewife's manual to us - what do you think?
