Kate Middleton pregnant: William Hill and Paddy Power already taking bets William Hill are hustling for bets on the child's hair colour (6/4 brown, 8/1 ginger if you're interested) Paddy Power offer punters the chance to gamble on the weight of the baby, with 5/2 the shortest odds for 7lbs to 7lbs 15oz. And prices of 33/1 have been bandied around for a twin birth. What do you make of the invitation to lay money on Duke and Duchess junior? Is it all part of the fun? Or does it seem a little creepy?
