my 6 week old was doing fine until a week ago. she used to feed every 2.5-3 hours, even at night. then a week ago, something strange happened, she started to cluster feed all by herself for three days in a row, and slept 5 hours at night!!!! then all of a sudden she stopped, and started feeding every two hours and sleep 4 hours at night.... does anyone know what happened to bring on this change?? :shock:
