I think that when a mother cannot feed her children, there is no room on her mind for much else. Whether or not I would consider improving her kavana to be a reason to feed her is a seperate issue. Why would davening for more things with better kavana be more valuable than davening for food from the depths of her soul? Who says Hashem can’t listen to her prayer for food and read all the rest of her needs? I don’t like the premise, but to answer the question, I would think her needs are a motivation to daven for her kids, but a distraction from davening for other things.
Amen to Golfer’s brocha.
