So if you put her down earlier for that 2nd nap, it doesn't help? I assume that's what you're saying. I'm thinking the nap is short b/c of the general state of being overtired.
Collin is very hard to read as far as tired signs go, too.
Collin is 11 months. I am happy with his routine because he is getting enough sleep. He still doesn't sleep a LONG night, but he takes good naps. I could possibly make the night longer, but I just don't want to mess with it. I am used to getting up early - I did it when I worked, and I have been doing it for a long time with him. Plus DH helps a lot. Collin's days are not exactly the same. Sometimes he naps 2+ hours at a time - when his night is shorter, but here is what he generally does:
6 Wake
9:15-10:45 Nap
2:15-4 Nap
7:30 Asleep
I guess things started to improve around 8 months. Part of it was me accepting things, and part of it was improvement.
It ALL started, though, because he got overtired, and it took me SO long to figure it out, and then it took me forever to do what it took to get him well rested. FINALLY I learned that he needed a certain amount per day, and even now, if he has bad naps or a bad night, I put him to be early enough to get him enough sleep for the day. For example, the other day, I put him down at 6:15ish, and he slept 6:30-6:15. It never backfires on me. Collin needs about 14 hours. Average for 6 months is 14.5 hours, and 14 hours for 9 months. For a while, I literally went by sleep hours for the day to determine his bedtime. Then after he was well rested, I started putting him down at the same time every night. That is when it really got better, but I couldn't do that until he was well rested b/c some days were bad with sleep, and a certain bedtime wasn't working. Collin will sleep 10-11 hours usually, so an early bedtime as a general rule didn't work for us. If I put him to bed at 6:30, and he was well rested, he might wake at 4:45/5. 7:30 pm is perfect to me b/c 6ish am isn't too early for me (like you said, I welcomed 6), and I enjoy a quiet evening.
I absolutely know how you feel about the planning - not being able to do anything b/c of the mess in the routine. I felt like such a prisoner in my house. And exhausted as you are... It was a very hard stretch of months.
I really do think things can get better.
I am happy to help in any way I can.
