She doesn't sound tired. how physically active is she during the day? i know a family with two kids who don't have a tv, and they focus a lot of energy on being physically active throughout the day, rain or shine. the kids go to bed between 7 and 8 pm every night. they kind of follow this school of thought that says kids should not be sitting down mch before age 7, but instead should always be moving. they say its important for emotional and pysical growth.
There are 80. Insomnia and an unwillingness to sleep is highly suggestive of one. The most common one is obstructive sleep apnea due to enlarge tonsils and adnoids. This is exceedingly common and can be bad on a childs health.
If you child snores.. see an ENT immediately. Snoring is not natural in children under the age of eight.
PS My four yr old has severe sleep apnea, as do I. It is genentically linked.
If we learn by our mistakes, I am working on one hell of an education.
My daughter was exactly the same (no sleep disorder tho). She is still a night owl. You can't make them sleep if they don't want to, but you can have rules about staying in their room, being quiet, etc.
My kids are the same. My oldest is known for waking and coming in to our room. I take him back to bed and sit with him for a couple minutes until he falls asleep. He's been waking b/c now that he is potty trained, when he has to go pee, it wakes him up and then he wanders. I wouldn't worry too much about a sleeping disorder. Not every child who has sleeping issues (staying asleep) has anything medically wrong with them. If that was the case, we would be at the doc's every day! If you think your child has something wrong see a doc, otherwise, I tried putting him to bed earlier (7pm) and it has worked wonders. If he does get out of bed, it's still early enough where I can get him right back to sleep at a decent hour. Good luck!!!
