She has suddenly started ignoring the counting to 3 (which always always worked before) and is no longer able to be coerced into doing stuff by me getting cross, instead she just laughs at me
She has started getting up from the table, shouting at us, asking for stuff rudely eg YOGHURT! after supper.
Not quite sure where to start with this as it has all happened at once, dh and I trying to be consistent - she has been on the naughty step twice int he past 2 days.
She has been a bit ill but this is beyond usual ill behaviour.
What tricks do you have up your sleeves for this sort of age?
