Glad to hear that sleep is improving for some!
We've tried several new options with sleep, but I think that it's only really starting to improve since her cold finally got better and she became more interested in eating again.
Firstly we wanted to stop the co-sleeping, so had me move in to her room into a single bed, but this caused me to have to be MORE awake to sort her out in the night. In/out the cot etc. Got fed up with that after a week.
Then we had a weekend away where all three of us had to share a bed, and actually we all had more sleep than usual.
So, came home and have started with me going to bed early, Pip in the cot (where she sleeps quite happily most of the time), boyfriend doing the 11.30 feed and putting her in with me from then on.
I've stopped breastfeeding at night, and she seems to be getting around to only waking up once after 11.30 before 7am. This is getting later and later, and she only has about 60ml, so soon hopefully she'll drop it completely.
I think probably that the week of me being in her room was unsettling because I was also packing in breastfeeding at night, we're away again next week but after that it'll be her into her cot and me into the single bed once she wakes up after the 11.30 feed.
She's eating SHED LOADS of solids though, which probably also helps.
