Typically how long does it take for you baby to be full from breastfeeding. My LO is 9 days old and if I bottle feed her she will be done in about 10-15 minutes, but if I breastfeed her she will stay on my breast 4ever! She gets sleepy and will suck a little, rest alittle suck a little more, its like she just wants to nurse forever. It makes it harder to tell whether she is full or not. And for this reason I kind of prefer feeding her pumped milk from a bottle because i know exactly how much she ate.
