My ds, who is 3, has changed in the last few days from a well-behaved quiet(ish) child into the child from hell.
He played up at playgroup yesterday, hitting another little and refusing to apologise (very out of character up until now), smacked my mother yesterday when she tried to put him in the car, and then misbehaved for dh & I right up until his bedtime last night. Don't know what has happened to him.
Another thing that makes me livid, is that when his grandparents are around, he misbehaves even more and he runs straight to his nanny or poppy every time I tell him to do something - as if they are his 'protectors' or something. Then they try to appease him, and it makes him even more naughty. I've just had it with him at the moment...
