lots of good advice already and I don't really have any more, but just wanted to add my encouragement and to say I am still breastfeeding my little boy, who is now 26 months, a couple of times a day. He went through a stage a few months ago of not eating much and wanting more boobie, also of tweaking the other nipple while breastfeeding, which was painful and intensely irritating but which he insisted on doing and would really fight me when i protected it from him! Despite all that I did to discourage him i think that he just forgot about it one day and hasn't done it since. it could have been the shock of his new sister arriving of course... ;o) best of luck, her appetite will soon come back and in the meantime she's not starving, and you can eat more cake!
