You're right, WIWO is driving everyone involved mad but you're also right that I need to find the root of the problem.
I tried giving him an uncapped nap the other day, like someone suggested - well, I say "uncapped", I actually woke him just before the 3 hr mark. BT that night was a disaster. He took 1hr 40 to go to sleep - the usual throwing his PJs, duvet out the cot etc. So that day looked like this
WU 6.20am (he had a NW for 40mins from 3am - think this was just a hangover from where he was getting over the chicken pox)
S nodded off in the car, managed to get him in his cot and he slept from 12.40 - 15.30
BT took him up at 18.30 and he didn't go to sleep til 20.10
He woke the next morning at 6.45am
So in the meantime we've gone back to our usual routine of
WU between 5.30- just before 6
S take him to bedroom about 12.30, messes about a bit but can sometimes be asleep by about 12.45 and we wake him after 1hr 30
BT take up to bed at 18.30 - asleep between about 18.50-19.30 after he's messed around
Do you think an earlier nap might make a difference? Think someone suggested this in an earlier post. There just seems to be so many combinations of nap length/time and BT time to try that I don't know what to try first. My mum (who looks after him when I'm at work) says she sometimes thinks he looks tired between about 10.30/11am and suggested I put him down for a nap then. What do you think - try it? And if so, should I cap or not? Or would this encourage EW? It does seem a shame that when he naps he could seemingly sleep for hours but we're usually waking him at 1hr 30.
It's just odd that having a nap at 12.30 for 1hr 30 and BT at about 18.30 seemed to be working for quite a while and we were getting morning WUs of about 6.15 with that routine (which suits me fine!). But the messing about at sleep time is getting worse and the WUs are getting earlier (although they are happy WUs). I also mentioned in an earlier post that he fell asleep one morning in the car for about 30mins and then wouldn't nap. He was shattered by about 15.30 but he went to bed at 18.00, asleep by 18.15 and except for a couple of minute NW at 23.00, he slept til 6.15am. I don't know what to make of that (if anything?).
Be honest, do I just need to give up, stick with things as they are (messing about for ages at sleep time, capping nap at 1hr 30 and EWs) and hope they improve???
