my 4 month old wants to be on the breast all through naps and much of the night. i try detaching her gently over and over, but she roots for breast almost every time and wakes up completely if i try other ways to calm her. i'm not opposed to nursing to sleep. it worked well with my older daughter, but it seems this one is a lighter sleeper. she also has GERD so i would prefer to keep her upright for a while after feeding and then lie her down, but she will not let go! she has a very sweet temperament but i'm exhausted and she needs to eventually learn to sleep without my breast in her mouth.
