Sometimes..not all the time but for some reason now & then my DD will want to nurse when she is tired to fall asleep. Most of the time I can just rock her or sing to her. But sometimes she just keeps crying & going for my boob. & I'm pretty sure it's not hunger cause it would be from 45 mins to an hour till her usual feeding. But if I can't get her to settle down & fall asleep so I give in & nurse her to sleep. Is this bad? I really don't want her to get in the habit of it! Also can you over feed a baby from breast milk?
