I know how you feel. Last night my 6 month old woke up at 10:30pm, 12:30am, 1:30am, 3:30am and then got up for the day at 5:15. I also am uncomfortable letting him cry, but do I continue this schedule until I go insane from exhaustion? From about 2 months until 4 months he would sleep through the night, so it is very frustrating to me that he will no longer do this. I guess my biggest problem with letting him cry is that I understand that the emotional reason for him crying should not affect his CAH, but the crying itself if it goes on for an hour or more does it become a physical stress? Guess I didn't answer any of your questions, just added some of my own.
