It is likely that she is just not tired enough. Is he doing something everyday that requires physical energy? On those days that you head to the park, or play place, does she sleep better. As a mother of 5 I have realized that running around during the day is the biggest encouragement to a good nights sleep. Ok, that, and getting out of her room:) You do need to let her be, she is old enough now for sure. I am not a mom who advocates Crying it out, but I would work on finding a way for her to put herself to sleep. Given the almost 3 hour nap during the day, I would also imagine she may not be tired until closer to 9-9:15 or so. Hope that helps some, good luck changing things a bit! ~A.~
