If you want to change the bedtime, do it by no more than 15-30 minutes each night, if not, they will likely go to bed later and wake at the same time. With the time change, did you slowly change his bedtime or did you change it right away by a whole hour? Might reverse and go to bed earlier and see what happens, he might wake at the same time getting more sleep, and then slowly change bedtime by 15 minutes later each night. Also, Since you aren't doing any night wakings, the amount of time he used to be up at night is now sleep time, so the total amount of sleep at night might actually be the same. When did he used to wake up? Mine used to have 12-12.5 hour nights when he woke 2-3 times at night. Once he slept straight, it became around 11 hours. He usually is asleep around 7:45pm and wakes between 6:45am and 7:00am. I also learned from Dr. Ferber's book that babies are much less motivated to return to sleep once they feel rested, so the crying doesn't work much then, which I know, contradits what Dana Obleman says, but I found is true. When we did sleep training with our son, we never let him cry when waking up in the morning or after a nap, even if only a 30 min. nap. He would just be good and tired the next time, which made him more motivated and went to sleep even faster. He could put himself to sleep within 5 minutes on the second night. No crying the 3rd. She does have some good suggestions though, I just didn't think that one worked. Congrats on making it a year breastfeeding!
