It's only been a day, everyone's body clock needs to adjust. Move times back by 15 minutes for each of his activities, such as meals, naps and bedtime. By the end of the week he should be swung around. Then when you go on daylight savings time in the spring, start moving his time forward the week before in the same increments. He's an active little boy and your body is trying to adjust to the difference as well. I've got a 17 yr old and it was difficult for him to go to bed because he had slept in earlier in the day. Getting up this morning was easier than normal (yeah!), but giving him another week he'll be bac to his 'normal' self.
