We're trying to get a handle on 12 wo's naps. She's hard to get down for her second nap, and nearly impossible to get down for her third. The first, however, is very easy. We have her sleeping from 8pm to 7:30-8am or so (with one sort-of-dreamfeed, and then one MOTN wake-up to feed), so probably about 10-11 hours total. She goes right back down at around 9:30am. Sometimes she wakes up normally after 1.5 hours or so, but it's no uncommon for her to sleep three hours or more for this nap.
Should we be waking her up after a certain amount of time? We finally roused her after three hours yesterday.
