My daughter has always been a great sleeper down at 7pm and usually has to be woken at 7am. However last few weeks she has been hard to settle and has stood in her cot shouting mummy or daddy and getting hysterical. Last night she woke at 2am shouting and when we tried to settle her then leave her for 10 mins she climbed out of her cot! Not sure what to do - should she be in a bed now and also why she is now difficult to settle, we both work full time so her being up all night won't be something I would want happening regulary. Any advice would be much appreciated so we can get her back to her routine!
