My son has an underwater themed nursery, with sharks, turtles and fish... along the bottom of the walls there is sand and coral. He has loads of fishy toys and mobiles etc it looks great! For my second child we are going to find out what it is, and if it's a girl I will paint a garden with a gate, flowers, butterflies and ladybirds etc. If it's a boy maybe a jungle with monkeys and snakes. Everyone tells me I should do this stuff for a living!
