Happy to share, gummy, just didn't want to hijack...
Main issue is v early waking (4 a.m.) and then only settling back to sleep if in our bed attached to my nipple. Sleep consultant advised that this is probably connected to night feeds - DD (6 mo, btw) expects to be fed and this expectation gets stronger as the night progresses and her sleep gets lighter. So the plan is to gently reduce night feeds and eliminate them altogether, and to try to re-settle her without feeding/taking her into our bed at early wakings. I'm doing this by reducing the length of time I bf by a few minutes each night and re-settling DD by patting/rocking/using a phrase I've introduced at bedtime as a sleep cue.
I'm only 2 nights in, so not much to report yet. First night, DD fidgeted for 45 minutes from 4 and then cried for another 45 (with me there, not left alone) until I decided to start the day. Yesterday, she cried on/off for 50 minutes from 4.50 and then went back to sleep until 7.30. Tonight, who knows...
The other main technique - which I've not had to use as I've sorted that bit - involves helping babies to learn to settle themselves, without the need for feeds/rocking etc. If they settle themselves at the beginning of the night, the theory goes, they will be more able to do so as they come out of each sleep cycle. You For me, helping my DDs learn to self-settle has involved staying with them with a hand on their backs, reassuring them I'm still there without actively doing anything to get them to sleep. With DD1, aged 7 months, that worked in about 3 nights. With DD2, I started the process at 16 weeks and it took a couple of nights.
Disclaimer: I know some would argue that at this age babies still need night feeds/shouldn't have to cry/should co-sleep. I'm not arguing with any of that if it works for the baby and the rest of the family. I'm just describing what works for us.
Sorry this has got a bit long - you did ask!!
