From an early age, my daughter has loved to paint. And outdoors on a big piece of paper is definitely one of her favourites ways to enjoy it (I think because she's allowed to get paint on as much of her as she chooses). Even my son really loves it, despite the fact that he's never enjoyed getting messy. Take a big roll of paper outside, fill a tray with paint, and away you go. I also put out a clean bucket of water for my son so he can be in control of how painty he is. Great for hand prints, foot prints and even nappy prints. Just watch the foot prints, as paint underfoot can get very slippery. At the end it's just a matter of hosing down the ground and children. This is can be as much fun as the painting was!
