Finn is 6 months and on a loose version of EASY. The reason it's not quite EAS is because his feeding is all over the map these days. He sometimes will do a 4 bottle day and others only 3 bottles. Some days he takes between 16 - 20 oz and yesterday he drained two bottles and had 16 oz before mid-afternoon

Nothing is consistent with this kid. I am squeezing in solids once or twice a day where I can just now...he really has no interest so we are not forcing the issue at the moment.
A times are finally at a level where I am getting decent naps again - this week anyway. We are using 2 hr 30 with wind down to have him asleep by 2 hr 45. That has yielded 1 hr 30 min naps and he has been going off for his nap without incident or crying. A bit of mantra or babbling, screeching the usual stuff but I haven't even had to shush/pat really at all.
I worked pretty hard and his morning A time is pretty much the same as his other A times. His final A time before bed is the longest...almost 3 hours (or more) some days because he just refuses a CN most of the time. We are trying everything from stroller walks to driving to straight rocking but he just will not sleep until his bedtime. Yesterday I even took him swimming in the hopes it would exhaust him and I could get a CN. DH got home early and saw that I was trying for a CN, we decided to drive him around because it wasn't happening in his room. Nope, he WOULD NOT SLEEP. So he was up from 2 - 6 with no CN.
However, our days are starting at 5 or 5:30 a.m. We leave him until 6 or 6:15 or as long as he will self-entertain in the crib but he is still awake at that time and counting as A time.
So here is what a typical day might look like (yesterday):
Awake 5:30 a.m. - in crib until 6
A
E 7:30 (he will not eat until ~2 hours after waking - he just will not take the bottle - he's not interested)
A
S in crib 8:00 - asleep 8:03 - 9:30
A
E 11:30
A
S in crib 11:50 (followed his cues for this one) - asleep 12 - 1:45 (first 1 hr 45 min nap ever)
A swimming!
E 3:30
S try to AP CN - even tried feeding to sleep for this one! went for drive at 4 - nope WILL NOT SLEEP
A bedtime routine started at 5:00
Bedtime (E&S) - asleep by 6:00 p.m.
Problems:
1) A times are not consistent...I just get working with a good A time...and then try it a second or third time and it doesn't work. This morning he was put in his crib at 2 hr 30 waiting for the sleep by 2 hr 45 which has worked almost every other day this week. Yet he is in there babbling, screeching, and thrashing his legs on the crib mattress (latest game). I don't get it! It's now 26 minutes since I put him down and I think he might have gone quiet. Yep he's finally asleep at 8 - meaning he was up from 5 - 8! I hope there is no 30 min OT nap monster coming.
2) Would his A time change depending on what time he woke in the morning? I mean if he was up at 5 this morning would he have a shorter A time than if he got up at 6? Like I know for me I am more tired in the morning if I am up at 5 rather than 6 - I have less energy. Is it the same for LO's?
3) He is normally doing about 10 - 11 hours at night. We are no longer getting 12, which we were for a while. But he is up at 5 or 5:30 no matter what time bedtime is and independent of day sleep. He can have a textbook EASY day and yet still he is up at that time. Could I try W2S is it just not likely to work given his length of night sleep?
4) What's the earliest you would put him to bed for the night? I mean some days with no CN it seems like I should be putting him to bed at 5? But will that just compound things??
I just don't know how to make this all function with starting our day so early. Yes I know babies can be early risers and I accept 6 or so but 5 just feels like we are getting up in the middle of the night. It's dark, there is no natural light to signal that it is day time...everything is quiet and I worry that we are waking our neighbours. It's really hard.
