We've had two relatively good nights in a row with DD. Now that she is no longer swaddled she seems far more able to self settle, so we are not having to go to her in between feeds. Night before last she fed at 10, 2 and 4, last night it was 9, 1 and 3. A massive improvement! Before we could be up with her a good ten times a night between feeding and settling her.
But there is a not so good side... I'm finding it really difficult to get back off to sleep after the 1/2 am feed, and from 4 DD will only sleep on me. This means that from about 1am I'm only getting about another hour of broken sleep.
I'm so tempted to just take her into our bed at 4 as she's sleeping beautifully on me now and will do until she wakes at 6. So I'm stuck sat in the nursing chair, which is comfy, but I can't sleep it in with her asleep on me. I just don't know if taking her into our bed would mess up her sleeping in her own cot. Plus I know that DH wouldn't sleep so well with her in with us. Given that he takes care of her for the first half of the night (until about 12-2) so I can get some sleep, I really feel that he should be able to get some good quality sleep in the second half, before having to get up to go to work.
I've always had issues with sleep and insomnia. It just seems so unfair that DD is finally starting to sleep better, but I'm not getting anymore sleep 
She also seems to have decided that she wants to sleep less during the day. She was having 2.5-3 hours across 3-4 naps, but today she refused to have a third nap and didn't even manage two hours. Still, she went to bed beautifully as she was so shattered, so as long as she doesn't get herself into such a state of over tiredness that she can't sleep, I'm just going to go with it.
At least being up from 4 every morning gives me some MN time
