this is crazy! went from 2 hrs to 20 min. over the weekend i decided i would let him cry for a while and settle back down - after 40 min he was so hysterical he was choking... he is not sick.. i dont know what to do! he sleeps a good 11 hours at night but he wakes up at 630 and by lunch he is EXHAUSTED and then won't nap. I tried pushing bed time back and that didn't work... don't know what to do?
