Prince George: first official pictures of 'little rascal' released by Kensington Palace But he's a little fighter. He wriggles around quite a lot. And he doesn't want to go to sleep that much, which is a little bit of a problem. The new photographs released by Kensington Palace today were taken by the Duchess's father, Michael Middleton, in a shady spot in the garden of his house in Bucklebury, Berkshire, earlier this month. In one of the pictures, the royal trio were joined by their black cocker spaniel, Lupo, and Tilly, a golden retriever belonging to the Middleton family. Lupo the cocker spaniel and Tilly the golden retriever joined the young family for their photo sesiion. The 31-year-old Duke disclosed that he had practised fitting his baby seat into the car before he drove Prince George and his wife home from St Mary's Hospital in Paddington, central London He said he was "terrified" that he would get it wrong and the seat would fail to fasten into the base in front of the world's media. I know there's been speculation about that. I had to practise, I really did. I was terrified that it was going to fall off or it wasn't going to close properly. So, I had actually practised with that seat, but only once before," he said. Recalling the moment when he and the Duchess emerged from the hospital with Prince George in a moment that was televised around the globe, the Duke said they were "happy to show him off to whoever wanted to see him." He added: "I think I was on such a high anyway. As any new parent knows, you're only too happy to show off your new child and proclaim that he is the best-looking or the best everything. It's nice that people want to see George, so I'm just glad he wasn't screaming his head off the whole way through.

The Duke changed the first nappy but admitted that he did not get up in the night to look after Prince George as often as his wife, who he said was doing a "fantastic job." He spoke movingly of how fatherhood has already changed him, saying: "I think the last few weeks for me have been just a very different emotional experience. Something I never thought I would feel myself. And I find, again it's only been a short period, but a lot of things affect me differently now.  However, the Duke admitted that, like many new fathers, he was now looking forward to returning to his job as an RAF search and rescue helicopter pilot so he could "get some sleep." "I'm just hoping the first few shifts I go back I don't have any night jobs," he joked. Expert view on the pictures by Eddie Mulholland, vice chairman of the British Press Photographers Association and a news photographer for the Telegraph for 20 years. They are lovely snaps for a grandfather to have taken, but in terms of the quality, they are not really what you want for such a historic picture. I would be pleased with them if they were for me and my family, but they look like they have been taken with a mobile phone or a consumer compact camera. It would have been better to have seen it done properly given that this is the official record of the future king. The photographs are very flat and there is not a great deal of contrast in them. They are back-lit, which is tricky to get right. You need to have a flash or a reflector where the photographer is to put some light back into the faces - the Duke, Duchess and Prince George are almost silhouetted. The parents are also out of focus in both pictures. You have to be extremely careful with focusing, and it is difficult to do that if you have got the camera on fully automatic setting. The photograph with the dogs is the worst. One of the dogs in the corner looks like a furry rug, and part of the Duke's head is wiped out by a patch of light coming through the trees. To get over that you would just have had to move the subjects until they were completely in the shade. The other picture is a lot better, in terms of composition it is fine, although the Duke's hand is cut off, which from a professional point of view is not ideal, and it would have been better shot in portrait rather than landscape format.
