Thanks again all

Feeling very frustrated at the moment as last two days she has only been taking about 450 ml. Last feed (3.5 hours since previous feed) she only took 50 ml from the bottle (under duress) - then offered her breast which she just bounced on and off again continually - did a bit of smiling and licking and did manage to get a let down -seemed to enjoy herself but just proceeded to get us both soaked with breast milk and really wasn't interested in drinking it!). Re-offered bottle 45 minutes later and she took about 5 ml - some of that 55 ml in total she managed to spit up as well. This feeding pattern seems to be more the norm over last couple of days (minus offering breast in the past). Before last few days we were getting closer to 700 ml via the bottle which is more what she needs. I guess something I am worrying about with breast feeding again is I wont know how much she is getting - and when we were in Torrens house they did test weighs and she would only take about 40 mls usually off the breast each feed (which is why we changed to bottle)- so even if she had 12 feeds a day (which I don't think I would have stamina for!) she still wouldn't be getting anywhere near enough.
Maybe she is just having a bad week and things will improve again soon.
