Oh that can be so hard How old is she again? What she is probably doing is boosting your supply for a growth spurt and also doing some comfort sucking . My next advice will not be accepted by all but IF and only IF you have NO nipple confusion at all and you feel that your bfing relationship is completely established then, MAYBE, MAYBE you could offer her a paci ( being in England you may call it a dummy?! ) My ds had a very strong need to suck all of the time and for a short period we did use one just so that I could go to the loo etc.. Why don't you try to swaddle her very tightly, give her a dummy, and put her in a swing for a little while? It is up to you but after 8-9 hrs of constant nursing I know that you are ready for a break?!?
