molly, I genuinely did not know what you wanted to hear. Sometimes people recount their own experience and want to have it affirmed, and their question is not really a question, IYSWIM. So I was expressing uncertainty as to what you wanted....
It is 100 per cent accurate that formula in the early days affects breastfeeding, undermining it. This may not have identical outcomes, of course, but it is undermining - for some, they may get away with it, and their supply is apparently unaffected. They may have a humungous amount of milk from the start, and the occasional formula bottle makes no difference - but the bottle is undermining, even so.
Undermining does not mean 'makes milk disappear' - but it cannot be anything but undermining to the process of breastfeeding.
It may be helpful to the experience of breastfeeding in individual cases - for example, the mother at the end of her tether may feel it is a good support emotionally and psychologically (though it is not the only way she can be supported in this way). It may even keep her going, as you suggest.
But physiologically, it is undermining and women need to know this. They also need to know night feeds are esp. important; that it is normal for babies to feed a lot; that help from partners can come in all shapes and ways and not just bottles.
So far, you have found all is well and at the moment you are very happy with what is happening, that's good :)
Sorry for mixing up
