Winton wet himself 4 times yesterday. He's four and a half and technically well beyond such problems.
Theories: bladder infection? too lazy to go to the bathroom? too distracted to go to the bathroom?
Last night I heard a sound like a panicked badger in his room. On investigating, I discovered Winton, in his room, running in frantic circles and clutching the front of his tiki-mask undies all while fast asleep.
Sleep running. This is new, and scary. I think I'll shut the baby gate at the top of the stairs tonight (good thing we've been too lazy to un-install the baby-gate).
