My 8 wks old DD2 is fully bf and so far very successfully, however since yesterday she had been really unsettled during feeds, stopping continuously crying and straining as if in pain, I do have a fast let down and she normally does swallow a lot of air during the first few minutes of each feed, but so far that hasn't bothered her so much during feeds, more afterwards with quite a lot of painful wind. She has also reflux, which I give her Gaviscon for. I don't know what to do, what is wrong? I don't think she is eating enough, should I give her some formula and see what happens? I have tried expressing but unsuccessfully. I am really sad as I really want to keep on breastfeeding her, but I am finding this so stressful and she does seem to be in pain. I must add that in between feeds she is quite happy, but does not last the usual 3 hrs. Thanks!
