For what it's worth, I definitely agree with gdubs point of view. I'm less clear on what you're saying though. When you say "unwilling to make personal sacrifices", does that mean unwilling to ever make any sacrifice? Or does it mean unwilling to make some under certain circumstances?
In my experience, my kids' sleep seemed to actually improve when engaging in the "extreme" practice of sleep training. That seems consistent with gdubs. How then, am I not "doing my best"?
