How to split money between kids/stepkid

Pooh- so by your logic, if the ex-husband of the triplets is able to increase his contribution to his kids in subsequent years, a portion of THAT should go to the stepdaughter? And if he objects (as he likely would) do we take into account that the dead mom doesn’t get to object- seeing as how she’s dead???

No compassion for a kid who lost her mom so young- and is trying to get to a college back where she has family??? She’s supposed to take the hit for the triplets- even though they’ve still got a living parent who can contribute- both now, and likely later on if they need help for grad school or just launching?
