I thought I'd cracked it, DS has been dry and clean day and night for nearly 4 months, but for the past week he's been wetting himself during day, and wetting the bed. I'm finding it really hard not to lose it with him, I can't think of any reason for it. Unless it's because playgroup has finished for summer - change of routine perhaps? I don't know. He doesn't drink that much, especially after 5, but doesn't seem to help. DH keeps saying put him back in nappies at night, but I think thats defeating the object, he's nearly 3.5 and starting nursery school in sept. Any advice?
