Sometimes Claire wont sleep either. If she doesnt sleep, I am not to worried. As long as she has some quiet time on her own, in her bed, then I am happy. I always wait for tired signs though and I only put her in bed if she shows me that she is tired or might be tired. Even if she doesnt sleep, and just has some quiet time, she always seems better afterwards. I wouldnt worry about it too much. Some toddlers just dont need as many sleeps as others.
