If your kids want something, you don't always have to rush out to the shops in order to keep them happy. Try and make what they want. Sometimes. For instance, a request for a cubby house can often be met with some cardboard boxes cut open and taped up. Cut out a window and make an opening door. Your child usually wants just the concept and is not so fussed on the trimmings. Often, making something gives them quickly what they want without the painful wait for them or cost for you.
