Sorry, one more question. Yesterday was a little weird, that was not typical at all (except for the fact that they are not very receptive to a catnap in the late afternoon). Usually it looks like this: nap #1 is 9:00 until 11:00. And nap #2 is 1:00 until 2:00. Should they have longer than 2 hours awake time there? Is that why nap #2 is usually short? And if they only sleep an hour for nap #2, how long should I wait for nap #3?
