Refusing bottle at 9 months

Isla is now 9 months old and I'm trying to get her to take a bottle, but she just wont. We have tried everything.... offering the bottle at different times of day, different people feeding her (have tried getting someone to feed her while I'm not there), different bottles/sippy cups, EVERYTHING but she just outright refuses. She did take about 100mls last week from a bottle but that was a fluke I think cause now she wont let that bottle near her. I'm starting to get really down about it and actually starting to hate breastfeeding her. I used to love breastfeeding but now it feels like such a chore cause she just wont have it any other way. I seriously don't know what else to do. My supply is diminishing so have been pumping 2-3hrly to try and bring supply up so she is getting enough but all the milk I express just ends up going down the sink, it seems like such a waste. What else can I do? This is really getting me quite down and I just cry at the thought of trying to get her to take a bottle now. I'm out of energy and would really love some time to myself one of these days but I always have to stay close to her so she can feed! PLEASE HELP!
TIA

Thanks hun, unfortunately I will be going back to work on Jan 10th (only part time) so she kinda needs to learn to take a bottle by then! So it looks like my last month or so I have left on leave is guna be a stressful one I do want to keep BFing her. My goal was always to get to at least 12 months but I'd love to be able to leave her with DF so I can go and have some 'me' time but i just can't. Had DF's work do the other night and I could only go out for 4hrs. She was at my Mum's and wouldn't take a bottle before bed. She did eventually go to sleep but then woke up an hour later hungry so I had to go home and feed her.

The feeds she does have during the day are pretty minimal to be honest, she has just recently cut WAY back on her feeding. She used to feed 5-6 times a day, now she has 3-4 but the feed during the day is only for like 2mins so I doubt she gets much so maybe she will be OK just feeding first thing in the morning and last thing at night (and her feed during the night at about 3am.... hopefully that stops when I'm back at work!)
A few times over this past fortnight, I have put her to bed without a feed cause she has been a fussy bum and not wanting boob, but she will only sleep 30mins then she is awake wanting fed.
And yup, she drinks water fine. She drinks a lot of water throughout the day cause I'm always worried she's not getting enough fluid from me.

Thanks again for your help x

Just saw this, hope it's sorted out now, but if not have you tried giving her the EBM in a sippy cup? My DD wouldn't take a bottle either, would just chew on it and scream till I fed her. So we tried it in a sippy cup and that worked (she still wanted to BF after it though LOL). When she was your girl's age DH and I went out to see a movie for our anniversary (a year ago on Friday actually lol) I left some EBM and the sippy cup for my mum and she took it fine - wouldn't go to sleep till I got home tho but that's another story (she still won't go to sleep for anyone but me although she weaned from BF at 13months!)

anyway hope that helps, worth a try
