Hello again,
I have finally managed to find 5 mins to get on the computer, I ahte typying long messages on the phone!
First I hope I ahven't raised your hopes too much, as I definitely do not have a miracle cure, but I have managed to "cure" dtg from the feeding to sleep thing (well mostly)
Secondly I totally empathise with the extreme tiredness times 2, as she has a brother who is not much better at sleeping, but at least he takes a dummy.
dtg is now 11 month and two weeks and like your dd she would only go to sleep feeding. She used to selfsettle at3-4 months for morning nap, but then she got worse and worse to the point where she wouldn't go to sleep in the car seat, pushchair or any other way than breastfeeding! over Christmas she had a few nights when she wokw every.two.hours!
I also wanted to stop breastfeeding so I started giving her a bottle at bedtime which she normally refused, but I gave her one with water during the day and graudally she started to first play with it, but eventually took a good amount. I would still breasfeed after the bottle as I wanted to make sure she had enough milk, but I would take my nipple out before she was completely asleep (this is a technique from teh "No cry sleep solution" by Elizabeth Pantley.
If she got upset, I would let her feed again, and would repeat the process for as long as necessary until she actually fell alseep in my arms rather than feeding.
She would then wake up as soon as I put her in the cot, and sometimes still does, but I try not to pick her up immediately, but stroke her back, and shush her, until she goes to sleep. Sometimes she sits up and gets upset and I pick her up again and repeat and repeat... It is tiring, but I was spending hours everynight trying to get her to sleep which was even worse, then I also had her twin brother to contend with..
It used to take me ages to get her to sleep, and now on a good day it's only 10-15mins: She has a bottle and then I rock her to sleep. Still not ideal but it's fine for me now. She also used to wake up again with 30mins to an hour after putting her down. While now she normally sleeps well til about 3am has a feed and goes back to sleep (except last night but that's anotehr story!)
Hope I have given you some ideas, my older two were both thumb suckers and also had favourite soft toy as a comforter. They were great sleepers and I was naively expecting the twins to be similar. No such luck with these two!
