Hi Ruth,
Thanks again for your thoughts

.
The catnap thing is tricky. There's almost not enough time for it, but leaving it out altogether leaves too long before bedtime. Will keep working on extending A time until it's long enough to accommodate this. And agree that we should bring bedtime forward a bit. Plan on doing this when I drop the catnap, as at the moment if I brought forward bedtime there wouldn't be long enough A time after the catnap and before bed - it's a tricky balance!
I have never dreamfed and except for the 5am waking bizzo, he's slept through the night fine without it. I breastfeed when he wakes (7.30am) after all three naps (approx 11.30am, 3.30am and 6pm) and before bed (8pm). I also give him 200ml of formula at this final feed (used to have huge milk supply issues and never dropped this bottle once that improved). The formula feed top up at bedtime seems to do the job of the dreamfeed. I don't feed to sleep. He always goes down awake and just about always drops off himself with no fuss.
I feel that he still needs the 5 feeds but am not sure how to fit them all in if we drop the catnap. I would love to see an 'ideal' EASY routine for a 6 month old to give us something to work towards. That would be really useful.
Yes, my DS does go back to sleep after the 5am wake. I think when he wakes at 5 he is wanting to start his day, but I haven't been letting this happen. He normally doesn't have other night wakings but he has on the odd occasion in the last couple of days - I think things are a little bit out of kilter for him as we try to work towards a new routine.
I religously used to do shh/pat to get him to sleep when he needed help, but have found this stopped working recently (which I believe is usual when they get to his age). I know I should probably be doing PU/PD but I've never followed through enough to do this successfully (every time I've tried he gets really upset and it's like he thinks I'm crazy). I've been rocking him in my arms and putting him back down when he's sleepy. I know this isn't recommended BW practice so perhaps I should change it. But as I've said he usually goes down fine on his own and I only do this when he wakes in the night and can't get himself back to sleep (i.e. the 5am wake).
When things are going well his nights are 8.30pm-7.30-8am ish, so 11-11.5 hours, so not too bad I think.
Could try W2S I guess for the 5am wake. It does sound a scarey concept though...
His A time is now slightly over 2.25 hours. I'm putting him to bed after 2.25 hours up, so add a few minutes for the time it takes him to fall asleep and that's where we're at.
Ok, sorry about the massive novel, but wanted to answer all your questions. Thanks again for taking the time to give advice.
