Looking for some tips really. DS2 is five, nearly six and he's an absolute nightmare when he's tired. He gets over-emotional, defiant, argumentative, pretends he can't understand simple information, screams and shouts - you get the picture. Obviously, the solution is to make sure that he gets enough sleep, but this is where we need help.
He has started not going to sleep when he goes to bed, he is exhausted, we have a bedtime routine but still no sleep. He goes into his older brother's room (who doesn't need much sleep so he's awake), comes downstairs, keeps his younger brother and sister awake through chatting so he's going to sleep quite late. He is now also getting up early as well and making lots of noise with his big brother and waking everyone else up.
I don't mind them being up early if they play quietly, but they don't and DS2 is clearly exhausted, yawning constantly and often horrible to be around because he's so tired. He's badly behaved on purpose to get a reaction which we try to avoid but we're only human. He has a reward chart for good behaviour which sometimes works but he's so tired he can't really think straight to consider the consequences.
Sorry for the essay but we've had a terrible morning so far and would like to try to avoid any more!
