Ds is 4 and half (ASD) and has been dry at night for the last 6 months. About a month ago he had a couple of bed wetting incidents and then was fine and now they are becoming more and more frequent (three nights in a row this week). I know in the grand scheme of things it's not a massive issue and he's still quite young but I am a bit gutted as it was great to have achieved it and it's always a worry if they go backwards on something.
