Thanks so much for all these great replies. So many great suggestions.
Last night was a bit different. Started out great - he slept from 9-2am! Then a 40 min feed but then wouldn't settle so was awake from 2-5, trying to get him to sleep sucking on my finger (won't take his dummy) then feeding again at 4am (i didn't want to feed him before that for fear of creating a snack 'n' snooze night) then feeding again at 6-7. The thing is he's also sometimes quite happy at these awake times, not seemingly hungry OR tired.
I simply can't seem to feed him to sleep after his night feeds. I do sometimes feed him lying down but he still doesn' go to sleep unless it's when he's been awake 2 hours. I also find it tricky to latch him on lying down and we both frequently end up frustatedand he might suck/feed/pull on and off/cry for more for an hour or so. Also have to feed my right boob lying on my left side which is pretty awkward so can't sleep while he feeds on my side. I certainly couldn't do it all without being awake!
I know the EASY routine and he usually is tired by 1.5hrs after daily sleeps anyway. Never feed him to sleep during the day. Can't enfore nap schedule and fussy rocking/shhshinhg etc on him as have to attend to DS1 so DS2 is simply put in sling when he gets tired and cranky.
Happiest Baby on the Block sounds good, though i already have Gina an BabyWhisperer and they haven't worked Wongy, good idea to write everyting down for 3 days - i will do this though will probs just conclude he likes to be awake from 1-5am!
Daytimes are fine, though demanding with two. If someone took baby for a walk I'd still have DS1 to deal with so bit pointless.
Cranial Osteopathy...i will find some more threads on that. He's ok in the evenings though, happy on DH's lap at the moment, just the blinkin' nighttimes, so maybe he's generally ok. i'll look into it.
bedtime ROUTINE? Yep, we do need it and I should probably do him an earlier bedtime too, though would this really impact the later night unsettledness?
Tonights plan at 1/2am feed is to feed him one side, then reswaddle and feed him second side in rocking chair with him on cover (good idea about moses basket cover Argon0). Start rocking as he nears end of breast and then continue for 5 minutes until I'm sure he's really sound asleep, then transfer both baby and cover to moses basket verrrry gently. If no success there, tomorrow i will just put him to bed next to me tonight and try to co-sleep all night so feed him as soon as he whimpers to see if it will stop him waking properly.
I'm a bit worried by those of you who've said they've experienced similar and their children didnt' sleep better until 2 years old
right, going to feed him now. I will let you all know how tonight goes. thanks again, i feel more positive and determined to sort it out now
