I'm currently doing my NQT year in Nursery and like you was trained 5-11 years. I never in a million years pictured myself with a Nursery class but here I am 5 months later I absolutely love it. I couldn't imagine teaching another class right now, and I've settled in so quickly. I've took time to read around the EY's and although it looks like the curriculum is changing, I've really got my head around it and find the planning much more enjoyable and creative! I say go for it, you've nothing to lose and plenty to gain!
