Sleep Habits

I'm really thinking that we need to work on Jacob's sleep habits! He sleeps great but I want him to sleep later!! Last night he fell asleep on the way home from the mall around 5pm. When we got home I layed him in his crib (fully dressed) thinking he would wake back up in a bit. I never heard a peep out him until 4:30 this morning. Yes, this was 11.5 hours of sleep for him but now we have been up playing since 4:30 am! Yesterday mornng he was up by 5 am, but he did take a nap at 7:30... I'm hoping that we both can take a nap this morning before 7:30 am.
