Bedtime

Bedtime is a popular parenting tradition that involves, to a greater or lesser extent, rituals made to help children feel more secure, and become accustomed to a comparatively more rigid schedule of sleep than they would sometimes prefer. It may involve 

1. stories, 
2. songs, 
3. nursery rhymes, and/or methods of coaxing the children into changing into their pajamas.
