Hi everyone 
I can't believe I'm posting on the Toddler board now. I miss my squishy baby! 
Our son has always been a pretty good sleeper. The problem we are having isn't with sleeping through the night. Once he is asleep, he will sleep upwards of 10 hours. The issue is that he won't GO to sleep. We start putting him to bed around 7:00 and he will NOT fall asleep until around 11. Weekends make it not so bad because he can sleep in, but during the week, we have to wake up at 5:30 for work, and he goes with us to go to the sitter's. When he doesn't fall asleep until 11, he is only getting maybe 6 hours of sleep. This worries me.
We follow a routine every night (Bath, PJs, Book) but he just will NOT sleep. He tosses and turns and fights it until he just eventually crashes.
Does anyone have any advice? 
I'm so lost, and I think he is now too old to sleep train

The other thing I would be questioning are his naps - what time are these/or is it. For example: if he is down to only one nap but it's in the afternoon, perhaps it's a too late nap which is leaving him 'not sleepy' when you are putting him down.
Also, how long are the day time naps. He might be sleeping a lot during the day, in order to catch-up on the lack of night sleep.
What is his normal routine during the day? Maybe this can help with some more advice.
