Both of my kids at 9-10months moved to a 11am-1:30/2pm nap. At around 15-18 months that time was pushed back until after lunch around 12:30-1pm.
At 9/10mth age my oldest didn't eat lunch until he woke up--but we have a late dinner because of when daddy gets home. My youngest needed his lunch before he went down. I just adjust his nap by a 1/2 to an 1hr for a couple days and see how he does.
