Thanks for your reply - I wish I had posted sooner...
I kept LO up today close to 3 hours and he slept 1.5 hours and did not wake at 40 min. So that was a real success!
The afternoon nap he was up for (A) 2hr and 45 min. He woke at 45 min, and I resettled him (took about 5 min) and he slept another 20. to total was 1 hr and 10 min. Thats much better than before!
So I hope that he won't actually wake at the 40 minute cycle..
Does this mean that the longest that he will sleep, on a 4 hour routine, is 1hr 15 min? If he's awake 2.75-3 hours, that leaves a nap of 1-1.25 hours.
How does that work..? Also what happens to the catnap, do we drop it and put him to sleep at 6?
Today I put him in the crib (after only a 2 hr A and he was in there for about 40 minutes but I don't think he actually slept.
So todays schedule was:
E - 7 wakeup and Eat
A - 7-945 - 2 hrs and 45 min
S - 945-1115
E - 1115
A - 1115-2 - 2 hrs and 45 min
S - 2-310 (woke after 45 min, and resettles to sleep)
E - 315
A - 315-515 - 2 hours
S - CN 515-6 (but I don't think he really slept at all. but he was quiet in the crib)
E - 7
BT - 730 (prob. closer to 8 till he really settled down)
Thanks again for your support and looking forward to your reply!
P.s. I sent LO to his grandma this week, and he totally refused the bottle of breast milk. As in, he just refused and ended up skipping that feed. Of course he woke up that night twice, and I nursed him early morning around 530 even tho I don't usually if he wakes then, I just resettle him to sleep, but I figured he was hungry. Which forum can I post this issue on? He is going to be started going to grandma regularly. Thanks
