I agree with you and from today morning I just follow his cues to see what happens, let him sleep as he wanted. he maybe a LSN, since he borned, his sleep is not longer , always 30mins, at 5 month, when the moring nap , I rocked him to sleep, but once put him down , he awake suddenly at the monment he touch the bed, he was very tired at noon since he fight the morning nap,so only two catnap during 5~5.5month, but great night (even more than 12hrs)at that time with one bottle formula around 2~4am. at the same time ,he stop the formula during night and sleep though all night from 19:30 to 6:15~6.20 , I think he need more sleep in day,so I trained him to sleep himself, at the first day he sleep himself, his nap became longer, morning 1.5,and 2hr noon, but in later days, he became wake earlier 5:00~5:30, always sleep again finallly wake at 6:45~7:00, everyday was different, and day nap became 40~1.5hr, seldom 2 hrs.sometims wake from day nap and after several mins fall in sleep again ,but alway unhappy if the nap was unconsistant. I never get 12 hours night when his nap became longer.
I tried to consistant 2-nap routine in march for one week, but never get a 2hrs , so he always tired around 18:00~18:30, I expect BT 19:00.so I just pull him to 19:00 or earlier BT sometime, at that time, no NW, always wake at 6:20, it's regretful I lost the records. then i try to cut he moring nap to 30 min, but still cann't get longer 2nap , during this period, NW seldom, but recently, EW every night, the longest wake always was around 4:00 , last over 1hr.
I am not sure how many sleep he need because of the mess now, so I will take coulple of days to take records, let him sleep when he want and as long as he want.
