Phal with Keiki - need to cut and pot?

[jkvalsvik]

Hello!

I just joined this forum to make this post and ask for your help! I have had my phalaenopsis for just over a year. Last year, I cut one of the flower stems and it has produced a keiki. It now has two leaves with three roots and one flower spike. The stem that the keiki is on is still green. See photos below.

What should I do? Nothing or should I cut off the keiki and pot? If I should cut it, how do I do it?

Thanks for taking the time to help!
