What are my options? Umbilicoplasty for post-partum belly button? (Photo)

I am almost 2 years postpartum with my final child and I can't stand the way my belly button looks. My skin was stretched to the point that my old naval piercing has both holes visible and there is some droop of skin. I was hoping there was a less invasive way to fix this instead of an umbiblicoplasty or mini tummy tuck but I don't know what my options are. Please help!
