Regardless of age, regular schedules and bedtime rituals greatly impact our ability to obtain sound sleep and function at our best, and the same goes for children — even more so.

Establishing and maintaining good sleep habits helps children fall asleep, stay asleep and awaken rested and refreshed. It may also prevent future sleep problems. Good sleep habits can not only take the stress out of bedtime, but can help make it the special time it should be for you and your child.

There are no hard-and-fast rules for sleep behavior and, as always, there is individual variation. Your child is unique. If your routine is working, then it is probably best for you. That said, some approaches work better than others, and the following guidelines have been shown to be effective.

1. Make sleep a family priority and part of your daily schedule, advises the National Sleep Foundation. Determine how much sleep each family member needs and ensure that they get it. Discuss any sleep problems with your child's doctor. Most are easily treated.

2. Learn to recognize sleep problems in your child. According to the NSF, you should look for signs such as difficulty falling asleep, nighttime awakenings, snoring, stalling and resisting going to bed, having trouble breathing and loud or heavy breathing while sleeping. These sleep problems can be evident in daytime behavior such as being overtired, sleepy or cranky.

3. Consistency. As in all aspects of parenting, consistency and follow-through are key ingredients for success. Without them, you just can't expect your child to learn or change behavior.

4. Teamwork. If you are co-parenting, it is important to discuss your strategy beforehand and work as a team. If you are beginning a nighttime program after having some difficulty with your child, explain your new expectations, if your child is old enough.

5. Set a regular bedtime and waketime. This sets and aligns expectations for both you and your child and allows you to plan the bedtime routine accordingly. Otherwise, you may have a tendency to slip and slide late into the night. In addition, this helps keep your child's internal body clock, or circadian rhythm, on a 24-hour cycle. Since our normal daily rhythms are around 25 hours, we would tend to drift out-of-sync with the 24-hour day, if it were not for external cues like a set bedtime, a bedtime routine, lightness and darkness.

There is not one ideal bedtime for each child, because sleep needs, lifestyles and napping patterns can vary considerably.

What Kind of Sleeper Are You?

Note that this does not apply to newborns and infants younger than about 4 months, because their biological rhythms or internal clocks are immature and not yet regular.

6. Routine, routine, routine. Kids love it, they thrive on it and it works. Routines set expectations and help train behavior; a nightly bedtime routine helps your child learn to be sleepy, just like reading in bed may put some of us adults to sleep (even when we're out of bed).

The structure of bedtime routines also associates the bedroom with good feelings and provides a sense of security and control. Routines can take the stress out of bedtime and help make it a special time, especially if you have more than one child.

Sleep Dos & Don'ts

This is a time to wind down. So calming activities, like taking a bath, reading a story, or perhaps a gentle massage are good choices. Keep TVs, computers and the like out of the bedroom, because they can arouse your child and keep her up later.

Let your child know what the routine is, including the time limits involved, and stick to them. It is often very helpful to give notice that time is almost up, like, "We have just three more pages of our story," but be firm and do not go past your limit.

Uncertainty breeds tension, and arguments may follow. A key goal in any routine is teaching your child to soothe herself so that she may fall asleep unassisted and put herself back to sleep unassisted when she awakens at night. Key to achieving this goal is for parents to leave their child alone long enough for her to go to sleep.

7. Dress and room temperature. Again, there are no absolutes here, but a rule of thumb is to dress your child basically as you dress yourself, keeping in mind that younger children often kick off the covers at night and are unable to cover themselves. People generally sleep better in a cooler (but not cold) rather than a warmer room.

8. Transitional object. Bedtime means separation, and that can be made easier with a transitional object, such as a doll, teddy bear, blanket or the like. This kind of object can provide a sense of security and control that comforts and reassures your child.

9. Room and bed sharing. Some parents may feel sharing their bedroom and/or bed with their child is more natural than having separate rooms, that it is important for emotional development. There may be cultural preferences as well.

From the point of view of obtaining uninterrupted sleep and considering various social and psychological issues, it is generally not a good idea. Everyone sleeps better alone — that is, we have fewer sleep disturbances and awakenings. Children in the same bed and/or bedroom also may not learn how to fall asleep themselves and tend to have sleep problems. Smothering is also a concern.

You Might Have a Sleep Disorder If…

Having a child in the bed with you may also have serious effects on your intimacy and sex life. Leaving your child with a sitter may become an issue as well. The longer the child sleeps in your bed, the more difficult it becomes to decide exactly when he or she should stop and eventually move into his own room. Sleeping separately is also important to help a child learn to separate without anxiety and form his or her own identity.

10. One last thing. Kids will always have that one last thing — kisses, hugs, a drink of water, using the bathroom. They can be quite inventive. Do your best to anticipate all this and get it done before getting in bed. And let your child know that once they are in bed, they have to stay in bed.
