Hernia - 8mo

Anna

My 8mo daughter has an umbilical hernia. Her dr said we'd keep an eye on it but most go away by the time a child is 5. It's not big but you can see it's slightly swollen on the bottom and it's a bit red inside her belly button.

What can I do at home to reduce the swelling and make it go away? It comes and goes for the last 4 months now, I've seen it 3 times now in 4 months.
