Interesting question (I apologize if this is a rerun, I'm relatively new to the group): 
Hypothetically: Let's say you have 2 children with different fathers. The new school year is approaching and it's time to go back to school shopping. Money is tight, so you ask the dads to pitch in on school supplies. One father says he can't afford to help out with school expenses. The other offers to pay for everything his child needs.
Question: Do you ask the providing father for help paying for the other child's supplies? Why or why not?
