blueshoes - Why would you think your baby wouldn't feed more during the day if you cut out night feeds? What else is he going to do? Mine certainly did.
Re "have to feed my babies because can't listen to them cry" - that is a choice. I didn't have a problem with it, because I knew the long-term benefits far outweighed the short-lived grief. Up for hours the first night, less than an hour the second night, sleeping through the third night and every night since then. (Besides, as I said earlier, she was crying the house down for most of the day and the night, anyway, and we hardly noticed the difference those two nights of sleep training).
Once she started to sleep through, DD was much happier and we were much better parents.
There will surely be other times when I will have to hear her cry because we, the parents, have chosen to do something for her own (or our collective) good that she doesn't like. And those will be OK, too.
I already had to hear her cry with real pain when stupid nurse missed her vein three times, but I held her tight with tears running down my cheeks because she had to have the blood tests. More prolonged misery when we took away the dummy.
I do understand what you mean, and it is hard, but honestly, I don't know how any of us survive parenthood if we are never to hear them cry.
