Hmmmm.... that's hard! Have you tried putting him in your bed at night, to sleep next to you? Do you run him around a bunch right before bed to make him tired? I've heard of that happening before, but not with a one-year-old. My son was confusing nights and days, so once I let him sleep in bed with us, the problem was solved. You could try reading The No Cry Sleep Solution by Elizabeth Pantly or Dr. Sear's The Sleep Book. They might have good tips for you. I would also go to www.askdrsears.com. He's got a ton of sleep information on his website. There is also a forum that you can post the question to, if you need more feedback. Sorry I can't help more!
