Lucy Wolfe - stay and support

[heartandheart]

My DS is about to turn 6 months and we've decided that we're going to try Lucy Wolfe stay and support as we are not coping with the night wakings... as I'm writing this we are on our 9th wake up of the night and it is only 3.30am!
He doesn't feed to sleep except during the night and he used to be able to self settle for naps and at the start of the night but never in the night (including half an hour after he's been put down!) he's lost this though since we moved him into his own room.

Anyway, my question is... how will I know if he's genuinely hungry in the night? At 6 months is there w possibility he might actually wake due to hunger?
I don't want to confuse him so that he can be fed sometimes and not others but I also don't want to feed him unnecessarily because how things are right now is not good for any of us.

Anyone who has used stay and support, I would love any feedback?

We've decided this is the way forward for us and have decided to use a gentler approach after reading a lot so I'm not looking for opinions on sleep training as I've read them all before.

Thanks!

New update! We've been consistent and definitely had rough nights where we've thought ah it's not actually working! BUT last night DS slept from half 6 until 6.50! He woke briefly at 7pm had a little whinge and went straight back to sleep without us even going in the room. He's not really using his dummy anymore either. We give it him when we put it in bed and he normally has a little suck and then spits it out before he goes to sleep!
