David Cameron has made no secret of the fact that he gets broody around babies, but his wife Samantha has ruled out adding to the family in Number 10. In another joint interview on the election campaign trail, the couple were insistent that they are not planning more children, with Mrs Cameron revealing her doctor has told her: 'No way, Jose.' She was pregnant throughout the 2010 campaign, and gave birth to their fourth child Florence in Cornwall after she arrived weeks early. Scroll down for video . Samantha Cameron has ruled out having another baby, days after she and husband David cooed over seven-week-old Regan on a visit to Chorley, Lancashire . Baby talk has never been far from the couple's mind as they have campaign across the country . Baby talk has never been far from the couple's mind as they have campaigned across the country. On Friday Mr Cameron celebrated his emergence from the TV leaders' debate unscathed with a visit to promote help for first time buyers. The couple cooed over seven-week-old Regan as they meet her parents, Robert Arron and Kelly Jeffers at a housing development in Chorley, Lancashire. Mr Cameron was heard quipping: 'Come on darling, maybe another one?' The Prime Minister, already a father of four, later admitted he could not help thinking about having more children when he was around young babies. On a visit to a brewery in Cardiff yesterday, Mrs Cameron, 43, pointed to a glass of Welsh Black stout she had been handed, and said: 'I normally just drink this when I'm pregnant' Campaigning in Cornwall, Mr Cameron told House magazine: 'Definitely, we are not having another baby.' Their fourth child Florence was born in the county in 2010 . David Cameron and his wife Samantha relax in Downing Street by watching Channel Four hit Gogglebox, the pair have admitted. The Prime Minister said the popular show was 'a very clever programme'. But Samantha went further, reeling off her favourite characters filmed watching television. She said she 'loved' Scarlett Moffat, the quick-witted northerner who become a cult figure over her sharp put downs caught on camera. Mrs Cameron said: 'I like the daughter in Newcastle. She's so funny, I love her, she's hilarious. I really think she's great. The Siddiquis are good as well.' After sympathising with the couple about sleepless nights he said: 'Whenever I see a small baby I feel broody, but don't worry, nothing is going to happen on that front.' Then on a visit to a brewery in Cardiff yesterday, Mrs Cameron, 43, pointed to a glass of Welsh Black stout she had been handed, and said: 'I normally just drink this when I'm pregnant.' The Tory leader - who recently ruled out the couple having a fifth child - quickly interjected: 'That is not an announcement!' Now they have moved to rule out categorically any idea that they might add to their brood. Campaigning in Cornwall, Mr Cameron told House magazine: 'Definitely, we are not having another baby.' Mrs Cameron agreed: 'We are definitely not.' She then added: 'The doctors have said 'no way, Jose'.' Mr Cameron chipped in: 'That's another story, darling… But anyway. No, we are not having any more. The last one was born not ten miles from where we are now.' Mrs Cameron gave birth to Florence in the middle of a family holiday to Cornwall in August 2010. The Prime Minister drove with his wife to hospital for what they believed would be a routine check-up. But four hours later he was by her side when she gave birth by caesarean section to their 6lb 1oz 'unbelievably beautiful girl'. It is believed Mr Cameron scrubbed up - wearing a gown and cap to reduce the chances of infection - for the delivery, which was three weeks early. The birth, at the Royal Cornwall Hospital in Truro, came a year after the death of the Camerons' six-year-old son Ivan, who suffered from cerebral palsy and severe epilepsy. The couple also have a nine-year-old son Elwen and 11-year-old daughter Nancy.
