Hi Jennifer, really tks for your response & support. It makes me feel better. My son has so many sleeping problems: not an independent sleeper, EW/NW, OT. They really drive me crazy. My son's A time is 3h40-50m btwn wake-up and am nap; 3h27-4h btwn am/pm nap. It's not long enough to have only one nap, and also difficult to squeeze in two naps.
To resolve his EW problem, I've tried late& short am/long pm nap approach for one month. Then I switch to long am/short pm catnap. The later method (long am) can sometimes bring me later wake-up (after 6:30, even after 7:00) but recently it also brings me short night sleep (less than 10hrs). For example. On 8/13 he slept from 8:30-7:05 (10h35m), am nap 1h33min (10:42-12:15, I cut it) and pm catnap 35min (4:17-4:52, I cut it) bed 8:30. The next day he woke at 6:16am. (9h45m) Then I need to go through several painful days. The results of this approach were so contradictory that I don’t know if I should stick to it.
Another problem of long am/short pm is that his pm nap needs to start before 4:30. After 4:30, it’s really difficult to get him any sleep. Even I can get any, his bedtime will be after 8:40 and the result won’t be good. His wake-up has been stuck at 5:50-6:40. Later bedtime won’t get late wake-up.
The worst is he doesn’t have any pm nap if it doesn’t happen before or at 4:30, leaving me a very OT baby and early bedtime.
I also can't push his am nap if his pm nap must start at/before 4:30 and for at least 35min. However, I really don't know if 35min catnap is too long or too short for him.
So the long am/short pm approach can bring me later wake-up, but it really risks OT.
The short am/long pm approach also confuses me. On 8/24, I tried it, and it was successful. (10h45min) On 8/26, I tried it, it was a failure. On 8/26, his am nap 35min (10:10-10:45,cut), pm nap 1.5h (2:30-4:00,cut) bed 8:30 and he woke up at 6:10 the next day. Only 9h40min night sleep.
Yesterday I didn’t intend to cut his am nap, but he woke up after 35min. (9:48-10:23) Then he had a very bad pm nap. Then it followed a very bad night.
Tonight he fell asleep at 7:06 (almost 6h A time) after 2.5h nap. I don’t know what will happen tomorrow.
Now everyday he wakes up at different time. (5:46-7:30) I really hope you or someone can give me some ideas as to how to get out of all these mess. Sorry for the long post and poor English. I wish you a good night. Tks again.
