Have you tried bringing her into bed with you? Kynan often has another little sleep if he's in bed with DH & I. What are the light levels like in Tori's room? It's been getting lighter earlier lately so it could be worth getting blockout curtains if it looks like that might be affecting her. Also what is the temp like in her room at that time of morning? Often in the early hours of the morning the temp can drop quite a bit so could she be sensing that?
