I'm confused - her first A time is 2 hrs and her first nap is 2 hrs, she's waking at 12 (because we wake her at that point), not what you are saying of a first short nap and then a 3 hr activity time, she never goes that long for A, she'd just pass out! Then her afternoon nap ends up being 2 tiny naps for some reason.
She naps best in bed.
