Joey was a similar sleeper...up to 13 hours at night, sometimes longer! At 16 months he was in the same place. I remember trying to keep him awake until noon...so difficult! We just had to keep him busy, busy, busy. I still give him lunch at 11/11:15 now, with a snack in the afternoon before dinner. He slept every day from noon until 3 up until last spring (he's almost 3.5 now), with 12 hours at night.
