David and Samantha Cameron have taken time out from their holiday in Cornwall to thank staff who delivered their daughter Florence last year.
They brought their year-old daughter to meet staff at the maternity unit of the Royal Cornwall Hospital in Truro, where Florence was delivered after Mrs Cameron went into labour unexpectedly during a break in the county.
They chatted with doctors and nurses and also to new parents about the trials and tribulations of parenthood.
Mr Cameron, while speaking with a young couple who have just had a baby son, joked with Florence and the others that she would not be able to have her own younger brother.
"I'm afraid you are not going to have one of those," he said.
"That's it for us, we are done."
The couple have two older children, Nancy and Arthur Elwen. Their other son, Ivan, who suffered from cerebral palsy and severe epilepsy, died aged six in 2009.
Florence, who turned one on August 24, was well-behaved and quiet during the visit to the Princess Alexandra Maternity Unit, where the Camerons showed her off to nurses and doctors who helped deliver her by Caesarean section several weeks early, weighing 6lb 1oz.
They chatted about Florence's early arrival, which Mrs Cameron said fitted in with the births of her other children.
"Mine were all early and that's why I think she was not too little," she told them.
