Congrats !!!!! first weeks BF is painfull and hard but then it all gets better and its a joy, and a amazing connecting expierence with your LO, at the beggining do whatever you can to settle her, you will have plenty of time for sleep training, if she is feeding well let her be, she canīt stay up for very long at this stage anyway and BF is a hard job for her as well so she will get exhausted just from eating,
best of luck !!!
