Some children will be later, it is how it has always been
Just passing on advice that worked for us
We had a good few months with soaking wet bed/bedding. I bought a comfortable (plastic one side, sheet on other) mattress cover, 3 cheap thin duvets (that fitted in the washing machine) so we had one on, one drying and one on the bed (very occasionally had to use blankets when all were wet) and persevered
I had to, for her sake and self esteem, give it a really good try ad she was ok with it (she knew it wasn't her fault) She didn't want to go secondary school in pull ups
We stuck to the water/loo regime, she took bottles of water to school and they helped us.
We stuck to it, to the letter and got results. We started last summer and have had 4 wet beds since christmas. She will always have some wet beds, even as an adult but in the main she is dry
We had one appointment at the eneurisis clinic and that was enough
I believe that you have to persevere and put up with the wet beds for as long as it takes and not give in to the ease of pull ups
Also, get a kylie sheet, fantastic things and realy help keep the wee contained
