Hi Jackie I don't think there's any must about it, so try not to worry. My wee guy is 21 mnths old and goes to bed at 8pm ish, awake by 7am ish, and naps for 1-2hours in the middle of his day. So he's getting anywhere between 11 and 13 hours a day. But at oru Mothers and Toddlers group, there's a huge variation in sleep times among kids his age. Some don't nap, and some sleep for much shorter periods at night. If he seems hapy and thriving, he may well be just fine on the routine he's in. If it were me, the only thing that would slightly bother me is how late he is up at night. Purely because it must mean that you get very little time to yourself, or alone with your hubby, so for that reason I'd try him with an earlier bedtime. But if you're happy and he's happy, then go with the flow.
