Which sleep issue to tackle first? (6 month old)

[Palacemum]

Background: I have a 6 month old boy, who slept 'pretty well' until he hit 4 months. Then BAM, the 4 month sleep regression hit and he reverted to regular waking... Like having a newborn all over again. I ended up bringing him into my bed after the 3am feed for a month or so, but with Christmas approaching (and wanting a sherry or two!) decided I had to get him back to sleeping in his own cot. I am not one for CIO so read the 'no cry sleep solution' and have definitely seen some success - he'll sleep in his cot now and I can now put him to bed awake at night and he'll settle himself at a 7pm bedtime (yay! We must celebrate these victories!)

However, he still wakes up lots in the night (at least every 2 hours) and I struggle to get him to nap for long in his cot in the day. I THINK his regular night waking is to do with his dummy as most of the time we just pop it back in his mouth and he goes straight off. So I'm not sure what order to tackle these issues in?

Should I try and wean him off the dummy first, and then work on naps? Or sort out naps first and then wean him off the dummy? Part of me thinks getting the naps sorted might be best as better napping = better night time sleep, and the dummy will help him to nap. But then any good work might be undone when I wean him off the dummy so maybe I'm best to bite the bullet and ditch this first?

I am a bit concerned about ditching the dummy as it seems to soothe him so much, day and night, but the constant waking is driving me crazy!!

(As an aside - he goes to bed at 7pm and I still feed him when he wakes around 11pm and 3/4am as I assume he might be hungry at one of these wakings. In between he just gets the dummy popped back in and some shushing)

Sort for the long post!

I'd ditch the dummy for naps to start, then look at tackling nights.
