Look at it from this perspective, my parents are 55 and I'm 19. I'm just finishing my first year in college, I wouldn't stress being 60 when they graduate high school, they'll just be happy to be there. Nothing wrong with being an older and wiser parent, I'm so glad my parents waited to have me and became established instead of rushing into kids.
Just from the opposite end of the spectrum. Hope it helps
