i have tried being all 'oh dear, never mind' and getting him to help clear up, ditto all that and clearing it up myself, talking in level voice asking why?, getting more exasperated and say 'oh ds2! not again', ... whatever i say or do he just cheerfully says 'sowwy!' smiles or giggles, or frowns when i say 'no, dont be sorry, just dont DO it anymore!' and then goes about his day (naked from the waist down.)
mostly, he goes to toilet if naked from waist down. but certainly not always. and hes out in the garden a lot, so im pretty sure he just wees wherever he happens to be out there.
so what do i do? bribery? sticker charts? talks? calm? annoyed?
tbh, i cant see any of it working... he just blanks me completely if i call his name and hes not in the mood to be spoken to (cue instant rage rapidly swallowed by me)
