How do you stop a nose bleed on a baby?

My baby of 1 year was standing by the couch he tripped and somehow hit his nose. I thought at first he just hit his face but when I picked him up his nose was bleeding. He has a runny nose so that doesn’t make it any easy cause blood will still come out even if I clean it. So I have just been wiping his nose with warm water + towel. That’s it.

It will stop and then it will continue to come again. His now asleep I haven’t seen blood at the moment.

But if it comes running down again how do I make it stop? Or what can I do ?
