Arrrrgh having bad day (not sure if this should go here or in potty training. 3 yr old DS did the thing I've always feared most today about child rearing - a dirty protest. Took him up for his nap, there was some resistance but this is normal. All was quiet (we don't use a monitor any more) but when I checked on him 90 mins later he was sitting up on bed muttering to himself with poo smeared all over his cot bed :( He's currently sitting in his cleaned room while I decide how to deal with / punish this behaviour. Any ideas?
