R sleeps around 10.5-11 hours overnight (usually 10.5 if it's straight through and 11 if there's a 4:30/5 am waking). He's 13 months. T slept 10 hours on the button until probably 14/15 months when he went down to one nap, so it definitely feels like more! But I am super jealous of everyone whose kiddos sleep 12 hours straight!
ETA: He naps 2.5 - 3 hours during the day. He is always yawning though. Can't seem to sleep enough!?
