Playpen use by 3 year old
I share joint cutody with my 3 year old son's father; my son visits his father every second weekend for a sleepover. At his house, he sleeps exclusively in a playpen, for all naps and overnights.
I'm sure I once heard that children over three years of age weren't to sleep in playpens because they could climb out/other safety concerns... Does anyone else know of any regulations following playpen use after a child turns three?
