Interesting how everyone sees things differently you think it's bad to 'train' your kids that you will come if the call for you I think it's worse for them to know that nobody will come if they do!
Our three year old knows that if he calls for us one of us will go and yes every now and then one of us will land up sat with him while he resettles but I'd much rather that than him not bother calling because nobody comes. We use a monitor as I see no need for him to get so upset I can hear him screaming over the TV before I go to him, we live in a small terrace for reference. Most of the time he goes happily to bed at 7 and wakes up at 7 the next day. The little one is only 8 months so to young to understand anything.
There is a middle ground! You make it sound like we neglect her.
What I'm talking about is when she was old enough to know how to play us and would call us back to go to the toilet half a dozen times or wanting more food even though she had been more than fed and, when old enough, warned to eat enough before bed time.
I guess I lived by the rule that, for the most part, if they're fed, watered and clean then they're ok and the crying was just for attention. You can tell when they're in distress versus crying wolf.
