For babies, it is important to establish a routine that differentiates daytime activities from night time activities to help them sleep through the night and also allows the parents to get some sleep. In the night time, babies should be put to sleep in their own cribs. If they do happen to wake up during the night, do not play with them. Change the diaper, feed them, or whatever is necessary with very little conversation.
b. small children
Small children enjoy the repetition of a bedtime routine: having a bedtime story read to them, saying family prayers together, etc. Stucture makes them feel safe and secure.
c. elementary children
Elementary children need a bedtime routine that will help them settle themselves down and declares the day is officially over. Dinner has been eaten. Homework is done. Backpacks are ready for the next day. The children can lay quietly in their beds and reflect on the day as they fall into dream land.
Preadolescents need a bedtime routine becase that are always trying to assert their independence. If they are not given a bedtime routine, they will try to rule the house. They will need to be told to put the cell phone away, turn off the computer, stop playing video games, and complete homework. They will even need to be reminded to take a shower/bath and to brush their teeth. Also, a parent may even need to tell them what time they need to be in the bed. Even though preadolescents seem more independent, structure is still necessary to assist them to stay on track.
Adolescents can benefit from a bedtime routine to wind down from the stresses of daily life. Reading a book, watching tv, or even exercising, may be ways to settle down from the craziness of life.
Hope this helps!!!
