Home interviews were conducted with mothers of 72 children, equally many of each sex in each of three equally large groups consisting of 1, 2, and 3years olds. Questions were asked about perceived accident risks, need of supervision, and need of safety measures in different rooms. The results showed that kitchen and bathroom were perceived as more dangerous than other rooms. Protective actions also tended to be perceived as more important in these rooms. Furthermore, the younger children the mothers had, the less risk and need of protection they tended to perceive. The age differences were in some cases larger for girls than for boys.
