This was something that my own mother struggled with during my own toilet training phase so many years ago. I was a chronic bed wetter, but my problem was medical. Some children will have physical problems, so if bed wetting becomes a real struggle after a certain period of time, you may want to consult with your doctor.

Start by limiting fluid intake right before bed. While some people don’t feel like this should be done, the reality is that if there’s nothing in their little body to expel, they won’t go. If you haven’t ended night bottles, now is probably the time to do so.

Don’t deny a thirsty child a drink of water. Some say that going to bed thirsty just fixes a child’s mind on water and increases the chances of nighttime wetting.

Keep bedtime calm. The risk of bedwetting can be increased if your child engages in lots of rough housing or even an exciting television program close to bedtime. When kids are excited, they tend to produce more urine. Keep her/him calm by having a quiet conversation or reading a story to her/him.
Before your child goes to bed, have her try to go to the bathroom one more time. Even if she says she doesn’t, try anyway. Your child might SAY one thing but when they sit on the potty they GO!

Consider not using training pants at night. Although you did not intend it, continuing to put your child in training pants for bedtime and expecting her not to have “accidents” may be sending her a mixed message. Initially, you should probably start with a diaper at night with praise in morning for a dry diaper, but soon after that, put them in regular underwear at bedtime.
Be alert for unexpected nightly visits. While your child gets used to underwear at night, s/he may have an accident and then wake up before you do. S/He will be uncomfortable and will either call out to you or get out of bed and pay you a visit.

Make sure the way to the bathroom is lit, even if only with night-lights. Draw a map with your child showing the way from the bed to the bathroom to help form a visual image. You may want to invest in an automatic sensor light in the bathroom that comes on automatically when someone enters the room.

Keep the house warm enough so the child won’t avoid getting up because it’s too cold. You can return to energy savings later.

Consider keeping a potty chair near your child’s bed if that will make things easier.

Practice “positive imagining” as you put your child to sleep. Help a child imagine staying dry all night and waking up dry in the morning. Talk about the pleasure of feeling dry, in control and grown-up.

Try whispering “dry” ideas into the ear of a sleeping child. This is something psychologists say children are often receptive to such “idea planting” during certain periods of sleep.

Let your child know that you know that he or she will stay dry at night II soon,” like other big kids. It is important to set up the expectation, but don’t subject your child to heavy pressure.

Remove diapers and replace them with training pants, cloth soakers, or disposable Pull-Ups only after a week or so of dry nights.

If your child does have an accident, try not to make a big deal about it. Reassure them that accidents do happen. Some psychologists recommend having the child clean up their own mess. This includes stripping the bed and placing the soiled sheets in the laundry bin as well as putting new sheets on the bed.

During this whole process, don’t focus on the accident and don’t make your child feel guilty for having an accident.

A plastic sheet under the regular sheets also will help you save the mattress.
Night time dryness does not always immediately follow day time dryness and could often take up to a few months or even years. It’s not uncommon for pre-schoolers and even some elementary schoolers to wet the bed at night. Just practice patience and be sure that there isn’t a medical reason for this problem.

Another issue during toilet training is how to maintain progress while traveling.
