I don't know what your parent's financials look like but my Aunt and Uncle helped my cousin years ago after her second divorce.
She wanted to go back to school, work part-time, and she had two young kids.
Even with all her grants and low interest loans, she barely was making it.
My Aunt and Uncle gave her some of her inheritance over a five year period. her two sisters know that she will get less than them after the parents die.
It wasn't a huge amount but enough to make a difference. Cousin didn't have to repay since it was going to be her inheritance.
It doesn't hurt to ask for help to move forward.
I know I would help my kids anyway I could.
My DD was a single Mom with no help from GS's biodad. I babysat full time for 8 yrs for her. She provided extra food and the diapers. She was able to buy a much better car and her own condo. I'm so happy I was in a position to help back then. That's what my family does for each other.
