DS is generally a really well behaved 2.5 year old but recently he's become a lot more naughty. It's generally high spirited running away but it makes things hard and can be dangerous at times. He's also started biting me a little occasionally and he's being really rude calling people mr poo/mr cow poo etc.
He thinks all of this is hilarious and won't be reasoned with. The naughty chair whilst being incredibly effective previously seems to have no effect, he'll just sit there and not care. There cones a point when u can't jeep putting him back on - if I have to go to work when I work for example.
Ive wondered about removing toys to a box but I'm loathed to drop the naughty chair completely as it did work so well.
Has anyone effectively combined other punishments with the naughty chair? Any other discipline suggestions? Positive encouragements like star charts haven't worked - in the heat if the moment he'd rather do what he finds hilarious than get a star or a sweet.
Thanks in advance
