Sorry I haven't replied sooner, I have having problems connecting to the site ...
Anyways I just wanted to let you know that things are going much better now. The quite dark room definitely helped but what I think also made the different is just having more patience, meaning that when she would come off the breast I won't try to latch her back on right away I just held her for a bit until she started to fuss at which point I would try to continue feeding her. I guess it was kind of like she was trying to hold out but then would still be hungry therefore would be more then happy to re-latch herself. At first feedings where lasting much longer, ~45min when usually she would feed between 20 min and 30 min, but now things are pretty much back to normal. I did also go back to the slow flowing nipples for the times that she would get a bottle.
Thanks again for all the advice !!!
