Our almost-3-year-old daughter has not been taking naps consistently for 5-6 weeks now; only about once a week. She has a toddler bed and remains confined to her room from 1-3 pm. She has become increasing destructive during nap time; my wife feels that this is because she is bored in a dark room. (She used to entertain herself to no end just talking to herself.) On most measures of whether she's ready to give up her naps she scores in the middle-of-the-road but more towards the ready, and lately she's stopped seeming tired after missing her nap.
We are tired of fighting with her over naptime (stay in bed, be quiet, don't kick things, don't tear up your room...), and expecting our second in a few weeks. So we are switching to a rest-oriented strategy, trying to design something that does not preclude naps. My wife and I have now had 2 debates about the correct light source to leave on during the rest/nap time. She feels that leaving the black-out curtains open is much more consistent with napping. I feel like leaving the black-out curtains closed (as we have been) and turning on the small lamp (maybe 40 watts at the far corner of the room from her bed).
I have two questions:
Which light source is likely the better choice?
Does this matter?
(To me it seems like the sun is far brighter and bluer at midday than the soft-white 40-watt lamp, and so it seems obvious that the 6ft x 30 inch open window would be less conducive to sleep, even though the sun never shines directly into the room. However, precisely speaking the brightness and spectrum apply to circadian rhythm setting rather than napping per se.)
