My daughter is 12 months and I talked to a sleep consultant about her. She sleeps 12 hours at night and about 5-6 hours during the day. It's normal at this age. They'll start sleeping less at about 18 months. Take advantage of it while you can. And yes, somedays they will sleep even more than that and it's usually a growth spurt. My daughter will a ton for a week and then the next week all she does is eat.
