Hi @Jenpri - I don't know your child but my experiences as a Mum plus a few decades as a kindergarten, pre-primary and Year One teacher suggest she is experiencing quite severe anxiety. If she was older she might be able to say to you, 'Mummy I'm feeling frightened because you've changed, our routine's been interrupted and its making me feel very wobbly, its like something's wrong and I'm angry because I have no understanding or control.' Disturbed sleep in a three year old is a signal - maybe call the Cancer Council or BCNA to talk this through. In the meantime remind yourself that as Afraser said, three year olds are very unpredictable - the food and toy they loved yesterday will trigger a tantrum today! Hugs to both of you!!!
