S.,
I am a mother of four children. They all slept all night from the time they were two weeks old. An old pediatrician who had raised seven himself, told me the secret! He said that Mother and baby BOTH need the sleep, worse than the baby needs that feeding. He said when he wakes up give him WATER ONLY, nothing sweet in it, just plain water. He may pitch a fit, but you hold your ground and refuse him anything but plain water (good filtered water). It may take a few nights for him to be convinced who is boss, but he will soon "decide" that water is not worth waking up for, and begin to sleep all night! This exact procedure worked with all FOUR of my children. That was years ago...the old-fashioned "discipline" of children is not looked upon as positive as it once was, but I am one who KNOWS IT WORKS, so that is the help I am offering. I have offered it to several others, they have also had perfect success. Your son may take a little longer because you have been getting up with him for these 7 1/2 months, but he will be convinced if you stick it out! If you don't show him who is boss soon, you will have a broken heart when he gets a few years older, so the sooner the better. God help you, is my prayer for you.
