Long post. Sorry. I am 3 days into what feels like a sleep regression. LO is 6 months old. I really don't think it is teething nor a growth spurt.

For the last 3 nights, he has woken up every 2 hours at longest stretch, and 10 minutes at shortest stretch. Prior to this, we have had more than a month of him sleeping quite regularly (3 wake-ups-to-nurse in a 13 hour stretch of sleep). Like a lightswitch it turned to this million-wake-up thing.

Here are the things that are new:

1) new kind of cloth diaper (yes, I will try to go back to the other one tonight, but maybe that's not it)

2) immunizations (well, can't do much about that, but don't really think that's the cause...he didn't really have a reaction to it)

3) nap schedule got thrown-off (immunization appointment ran 2-plus hours behind and LO ended up SUPER late for 1st nap, and then after that we had 2 hours of driving, twice that day, so his whole schedule got messed up that day, 3 days ago)

4) he's been taking a double-nap in the morning ever since then (because he is tired, he wakes up, babbles and I leave him so he can sleep more, which he does.........but maybe I'm doing the wrong thing as this is yet again adding to an 'unusual' pattern.

5) he's fighting the afternoon nap, and actually the 2nd day I let him stay up all afternoon, foolishly thinking that maybe he really didn't need it because of the double-morning nap and because maybe I thought if he was really tired he could sleep at night. YEsterday I made him take that 2nd nap, and it took me an hour to get him to sleep (very unusual) and it STILL didn't cure our night-time problem.

6) 4 days of oats introduced into the solids-eating schedule (but I don't see any other reaction from it?)

Since we're just 3 days into this issue, I want to fix it before it becomes a habit. This happened at the 4 month sleep regression and I just put up with it for 5 weeks or so until I finally 'cured' it with 2 nights of CIO bedtime, but I really don't want to CIO again if possible.

What should I do? I feel like I want to change everything but the scientist in me knows I should change one thing at a time, but I also don't want to drag this out any longer than I need to. I don't want him to CIO, for example, if he might be unwell or uncomfortable.
