Hello everyone - as I was the OP on this, I thought I'd update as it may be of help/interest to some.
Over the last few weeks since I posted about this, I have spent a small fortune on bottles and teats of every shape/size and description. None of them went down well with my little girl (she's now 14 weeks) and she either was completely uninterested or screaming the place down when we tried.
I had my MIL, SIL, friends, neighbours and of course my husband all try to get her to take the milk from a bottle, but no way would she. We tried every possible position that was different from how she feeds from me but still she would not have any of it.
Last week, feeling really disheartened and thinking my little one was going to be one of the ones who 'never took a bottle', I though I had nothing to lose by trying her myself, with my original tommee tippee bottles and teats and see what happened. I took her and my older daughter out to the park and while my eldest played, I began putting the teat in and out of my littlest girl's mouth as she chilled in her pram - like a game. She allowed it and before she became upset, I stopped. Then I'd do the same a few minutes later. On the fourth attempt, she took a couple of sucks. I immediately took it away as before, then on the next attempt as soon as it went in she took a couple of sucks. I didn't want to push it so that was the end of that bottle feeding lesson.
The next day, I put 2oz of milk in a bottle and while holding her upright, over a 15 minute period, managed to get her to drink 1oz. I was elated!!!
The next day I did the same only she drank the whole lot!
Two nights later, I was able to give her 4oz and we've not looked back! It's all been done by me which is what everyone said would never work, so it just goes to show that one size does not fit all.
In retrospect, it's nothing to do with what bottles I used, or maybe even who did it, more distraction and patience while my little girl learned a new skill. She perhaps needed it to be me who taught her
Anyway - if this gives even one person a bit of hope that they can sort out this type of problem, then this update was worth its weight in gold!
