Hi there, welcome to BW! I am happy to hear that BW has worked for you in the past

Let's see what we can do to help James.
You can probably guess why...I breast feed him every time he wakes! Eeeek. The extreme tiredness made it easiest option, fool that I am! We have tried controllled crying and it is too awful, so am keen to do pick up/ put down.
Well you already know that BF is a prop. He is not using it for sustenance at this point, he's using it to get himself back to sleep. So yes, it needs to go if you want a true independent sleeper

CC is not something in line with BW or Tracy's methods, it is felt that it breaks the trust with your LO. We do not leave LO to 'cry' on his own. That said, at 11 mths you need to be able to distinguish between his various cries...there are 'I need you' cries vs. a mantra or self-settling cry.
The first thing that stands out in your routine is that he is possibly getting too much day sleep and at the wrong times.
He is entering something known as the 2-1, it typically begins around 10 mths and continues until LO is on one nap, that can be 12 - 18 mths. They drop some sleep needs but are not able to cope being on one nap just yet. So we have to put a limit on how much sleep they have and when to keep nights intact.

I think one of the reasons he's waking at night is because he isn't getting enough activity time. LO's of this age group are doing between 3 - 4 hours A time, most doing the longest stretch before bedtime if they are doing a long PM nap. He has a very short A time between naps...he's sleeping decent naps, is he an Angel or Textbook baby? I think he's just used to being put down at that time so he goes but ideally after a long AM nap he should be able to go longer A time.
Action/Solution; Get baby to sleep through night, stop breastfeeding in night.
So from what I can gather I need to; Reassurance by patting when lying or just saying "sleep time now" when he wakes and cries. (he cries at night but doesn't stand). Do I pick him up? He sometimes cries in the day too, do I do the same? He did have the ability to get himself to sleep from a very early age, but I have mucked it up. Could someone please tell me what to do??
Do I stay in the room and pat him or stand there. Do I get a blow up bed in there and stay in the night for a few nights (scary prospect as may be the new prop!) HELP
Yes there are two ways to go at this. You can do PD with WI/WO or GW - given that your son is a comfort feeder and used to that personal attention from you, I think you might have better luck with GW. It's a gentler approach if he has never slept independently.
