Recently, there has been a great demand for day nurseries in Japan. The purpose of this study is to consider whether it is relevant to use the floor space of eating, napping and playing per person. We observed zero-year-old-children in detail during their stay in their nursery rooms. We also measured eating, napping and playing spaces of nursery rooms. 5 nurseries fulfilling the following criteria were selected; eat and nap in the same room, 6-12 children for each class, 3.0 �-5.0 � per person in a room. As a result, we found that eating and napping space is 1.02-2.42 � and 0.91-1.83 � per person, respectively. Therefore, we figured that the necessary space of eating was 1.68 � per person and of napping was 1.23 � per person, respectively(4.11 � per person in total) in order to make comfortable nursery room. In case the development levels of children who compose a class differ widely, it is impaired for them to crawl freely and safely.
