Apparently limiting intake before bed only makes it more difficult to train your child. There are many different things you can try to help with bedwetting, but I would honestly say that if your child is 4 years old and wetting only once a fortnight usually... you have nothing really to worry about. The suggestions that have been made about using shower curtains or connie bed pads etc will help to eliminate the stress of the situation. I was told that you should not reward a child for something they have no control over.

I will tell you my story, not because I want to scare you but just so you have some knowledge.
I started out by trying a spray that is used under the tongue, which you can buy over the counter from a chemist. I had no luck with this product. I tried limiting drinks, which didn't help, and doc's said that it does nothing to improve the situation. I had my DD to a bedwetting specialist who tried exercises. Measuring urine. Making sure drinks are up through the day and keeping a record of all this information to see if anything changes. This didn't help with my DD. If this doesn't help, there are bedwetting alarms you can try. This didn't help with my child as she would just wake up and turn the alarm off and go back to sleep. I have tried her on tablets such as minirin melts and tofranil (by prescription only). Nothing has worked. I have been going to the urologist clinic for almost 12 months, had U/S, urine tests, but still have no answers at the moment. I am beginning to think my DD is just too lazy to get up out of bed and have since started getting her to do her washing as she is nearly 11yrs old and is wetting the bed about 19/20 nights. When I was at the urologist clinic earlier this week. I told the doctor my frustrations. They were meant to be doing further tests but apparently that was a misunderstanding. I need to wait until we get into the enuresis clinic for any further testing. They have given her tablets (tofranil) to take again even though she was on them for about 6 months with no improvement. I asked the doctor why is there such a long waiting list, after all I haven't heard of anyone else her age wetting the bed everynight like she does. I thought I was alone. But he says I am wrong, that is why there is such a long waiting list, because their is many children her age or similar who are wetting the bed just as much.

The only other thing I could think of besides lazyness is, well for my daughter anyway, psychological. I have had her to a psychologist for some time but I don't think it is doing much improvement eiter.

Anyways so that is the road I have travelled down with my DD. I hope you will not be travelling the same road. I'm sorry I couldn't give you any answers in the end for my DD case, it is a long journey and I am still waiting.

Good luck
