Hello all, sorry I haven't been keeping up. I still haven't caught up with the thread but just wanted to update you all to give you some hope.
Things have been up and down with DD2, and I have continued to feel tired and emotionally down. I have ulcers and painful spots on my tongue, both signs of being run down. However in the past 2-3 weeks DD2 has started to sleep through, patchy at first, but at the moment she is fairly reliably sleeping through.
We started a month or so ago stopping immediately feeding her at night and trying to settle her instead. Through persevering with that we managed to get down to one feed, if not just one waking a night. This from at least 2-3 (and that's after I've gone to bed). But with the rolling and being more active she has been a PITA to get to bed. I couldn't feed her laying down on the bed to sleep then leave her as she just wouldn't stay still. She is now in the spare room and I have taken to feeding her in there. She was still a pain though and in the last week (though still sleeping through - that took some time though, was 1 in 3, then 2 in 3 nights on average, now most nights) it's been taking 3 hours to get her to sleep, either not feeding to sleep or being asleep but waking as soon as I moved her, multiple times in a row. She was also waking up at least once in the 8-11pm period needing resettling. These are the things that we have done which may or may not have contributed to any of this:
Restricting (or trying to restrict) naps after 3ish
Black out curtains (I've always been against these, never used them for DD1 but wanted to try everything)
A fan in her bedroom (I originally did this the other day when it was boiling, but now it is cooler we have kept it one in the eve as I think the noise helps mask other noises i.e. DD1!)
When I try and put her down and she stirs and roots around, instead of either putting her back on the boob or putting her in the cot with my hand on her and hoping for the best I keep hold of her until she has drifted off again
She is waking in the night but because I am still wearing one earphone and she is in the next room we don't hear it unless it is really loud, so not going to her at every stir and she is going back off
We also did one night of CIO
, we had to, she wasn't screaming but it was cry stop, cry stop, settling crying IYKWIM, though it did go on for about half an hour or so. The thing is she wasn't feeding to sleep, or wanting to be settled and the night before DH tried sitting in the room with her for an hour and a half which didn't help either, so we thought it might be better to just leave her. That was Sunday and it does seem to have helped. But just to reiterate, it wasn't continuous crying.
So it has been a long journey, we seemed to get one thing sorted then another went wrong :(. It's still not perfect, and she isn't napping long in the day now. But you can't have everything!
I'm not going to leave the thread yet, that would be stupid! But I really hope any of this might help someone else.
