Nothing particularly new or innovative, not very many things that real people with real income could implement. Its clear in many cases that the designers dont actually know any kids (or have never been kids?!), and some of the designs are just bizarre - four or five beds in a room where the owners are clearly millionaires and could split things up a bit! There are a few cute (again, not new) ideas, though.
