How and when did you institute "quiet time" if nap time isn't happening or isn't long enough? My twins are 23 months old and one guy generally naps 2 hours, his brother, not so much. Problem is they are still in cribs/pack n play. They nap in separate rooms. My guy who doesn't nap well also has the habit of throwing everything out of his crib, so if he's not sleeping, he doesn't have anything to play with, either. Meanwhile, his brother naps his 2 hours and will play quietly w/ toys in his crib before/after the nap. How can I get the lesser-sleeper to do the same, given that he usually takes to screaming when he's not sleeping, which wakes up his brother?
