I really hope I'm just being paranoid here but I'm in such a state tonight over this.
Dd is almost 5, she is overweight at almost 4st
(she has always been quite chubby, even as a baby but has gradually gained more over the past 6-12 months, we have noticed it and are taking action, know what to do going forward etc)
She has had some secondary bed wetting for the past 6 months, I put it down to her drinking too much water before bed so stopped her having drinks past 6pm, this works some nights and doesn't others.
Recently she has been saying she is itchy down below, and over the weekend said that it hurt when she had a wee.
I looked into utis in children and read that bedwetting is also a symptom (never knew) so had her at the docs today, doctor examined her (all looked fine) and I have some pots to send in a urine sample in the morning.
I've been looking into more reasons for bedwetting in children, one of them is diabetes and I think because we've just came to the realisation that we need to do something about her weight gain and now panicking that she had diabetes and that we've caused it by letting her get so overweight. 
I really did think it was a UTI but now not so sure as she's been peeing fine today and hasn't complained of any pain. So now my mind is saying diabetes and I'm so worried. I can't do anything until the morning but I'll ask the gp to test her urine for that also.
She's fine with in herself, happy and full of energy, rarely poorly, sleeps well, doesn't have a huge thirst or need for urination.
Really she seems fine other than this occasional bedwetting and pain/itching when weeing.
Does it sound like diabetes??
Sorry for the ramble but I have pretty bad anxiety so going through the roof with worry.
I know I just need to see what the doc says tomorrow but just needed to talk it through with someone
