Hi, when we switched to the 4 hr, dd only ate 4x in day, w/last feed at 6. She then would wake up once around 2 to eat, and then not till am. She wasn't overly hungry at 7 am, so I was thinking of how to eliminate when one evening she decided to wake, and was crying. I was trying to put her back to sleep, but decided to feed, and then she slept right till morning It was awesome. She is only bf, but now eats solids 3x a day. From about 4 mos she was eating at this schedule, then at 5 1/2 mos, she started the evening feed and goes till morning. She really doesn't have a 4hr easy, but it works for us because she sleeps well. She eats at 7, 10:45ish, 2:30, 5:30-6. In bed no later than 7, and gets nursed around 9:30. Only prob is she is waking early in am, but not to eat, just to play! Good luck, it definately made a difference going to the 4 hr easy.
