Believe me, I thought the same. I also wondered after the days of getting only 90minutes in nap time per day, whether it wouldn't have been more restorative to have them occur in one nap, rather than from two crappy ones, iykwim. No offense to BW ideology, but it has me so worried about anything and everything causing OT, that it makes me think that one nap may cause more harm than good. I really honestly have no idea what I'm doing anymore, nor do I trust my instincts in any way. I am totally guessing at A times and hoping for the best. Yesterday we did a 20 minute catnap from 410-430, bt of 7pm, and she woke at 5am without any NWs. This has thrown me for a loop. I may try it again tonight, and try for a 730 or 8pm bt.
