DD has always been a good sleeper and had a bedtime routine of 7pm. Over the last couple of weeks, she has been a complete nightmare. Delaying bedtime, coming out of her room multiple times, not listening to instructions and on it goes. We've tried being firm, we've tried reward charts, we've also tried cajoling her and being super positive. Nothing seems to work and it's exhausting. Any pearls of wisdom as she's slowly wearing us down? Is this normal for the end of her first year at school? We wonder if she's just exhausted and it's manifesting itself in this way or maybe it's just a phase. Either way, any help gratefully received!
