Only 10m here but we dropped to two naps at the start of the year. DD gets up at 7:30, goes down about 9:45 for an hour or so, and then again at 2:45 until 3:30ish. Bed at 7:30. She used to be a chronic catnapper, it drove me crazy. She's pretty good now.
We've been confined to the house for naps since about 6m, but it doesn't bother me that much. I'd rather she had a sleep and was cheerful rather than missing it and being a nightmare! If she naps well in the day she sleeps better at night, and I'm slightly obsessed with her night sleep, for my own sanity more than anything!
