I've posted about this before in the potty training section, but I think that maybe this section might be more appropriate...
I just wanted to share this in case it is helpful to anybody else.
About 6 weeks ago I took our DD to the GP as she was still bedwetting most nights and we had tried everything we could think of to help her, I was literally at my wits end.
The GP sugessted we try stretch her bladder by giving her loads to drink every day, up until about teatime.
Within about 2 weeks of trying this, DD was dry at night! She had one accident, about 3 weeks ago but other than that, nothing!
I know there are loads of reasons kids wet the bed and this method might not work for everyone, but I really wanted to share it in case it helps anybody else. I certainly wish I hadheard about it years ago!
