I cannot tell you that I did this, but know someone who did it with 3 children and it worked on all 3. My son was already past this stage when I met this mother. Her doctor told her, that if the baby is crying in the night, like it wants to eat, DO NOT feed the baby milk in any form. He said to give ONLY water in the night, period! The baby may fight it at first, but if the baby is truly hungry it WILL drink the water. If not, you're going to have a fussy baby for a couple of nights, but if you are diligent and only give water every single time without fail, and the baby figures out it is not going to get milk within 2-3 nights you should have a sleeping baby. This is supposed to straighten out their sleep pattern AND they will eat better during the day. And just think, when the baby is crying and you don't know if you can hold out thru the cries, water is not going to hurt the baby.....the baby is just telling you it wants something different. Kind of like us getting salad, but wanting chocolate. I do hope this works for you. I remember those sleepless nights feeling like the "edge" was not far away from you. You will look back fondly of this time believe it or not!
