19mo & I have him in the cot about 7.30 & he doesn't get up before 7am BUT sleep would actually be closer to 8-6.30 on average & naps from 1.75-3.15 (in the cot) , mostly about 2 -2.5 hours sleep, so about 12.5 on average sleep ( his 3yo brother often sleeps the same)... I have found with ds#2 his down time = the average, but his sleep is usually less, he has always had a wind-down & wake up time in the cot, where he just plays (sometimes with me in the room with him, others on his own) or if he wants to leave his room he will "chill" on my lap for up to 45mins on waking.
